C++ 101

I'm dreaming to send homework to my C++ programing lecturer full of strange #defines and make the code compilable, runnable and working well
He would feel the black side of cpp😈😈😈

When you don't find what is wrong with your code so you do some shit and it works miraculously

I'M AN IDIOT.

I accidentally typed the wrong command when I was compiling my C++ code with GCC, and guess what?

My .cpp file is gone. The .exe is still there, but that's useless to me right now.

It wasn't an important code, just something I recently started on, but I can't believe I did something so ignorant.

So I have a teacher that when he use "C++" it is basically C with a .cpp file-extension and -O0 compiler flag.

Last assignment was to implement some arbitrary lengthy calculation with a tight requirement of max 1 second runtime, to force us to basically handroll C code without using std and any form of abstraction. But because the language didn’t freeze in time 1998, there is a little keyword named "constexpr" that folded all my classes, arrays, iterators, virtual methods, std::algorithms etc, into a single return statement. Thus making my code the fastest submitted.

Lesson of the story, use the language to the fullest and always turn on the damn optimizer

Ok now I’m done 😚

Man, I think we've all gotten way too many of these.

Normally most interactions that I have are through email. Eventually some would try to contact me via phone. These are some:

"Hey! We are calling you from <whatever company name> solutions! (most of them always seem to end on solutions or some shit like that) concerning the Ruby on Rails senior dev opportunity we were talking about via email"
<niceties, how are you doing, similar shit goes here...eventually>

So tell us! how good/comfortable would you say you are with C++?"

Me: I have never done anything serious with c++ and did just use it at school, but because I am not a professional in it I did not list it in my CV, what does it have to do with Rails?

Them: "Oh the applications of this position must be ready to take in additional duties which sometimes happen to be C or C++"

Me: Well that was not anywhere in the offer you sent, it specifically requested a full stack Rails developer that could work with 3 different frontend stacks already and like 4 different databases plus bla bla bla, I did not see c++ anywhere in it. Matter of fact I find it funny, one of the things that I was curious about was the salary, for what you are asking and specifically in the city in which you are asking it for 75k is way too low, you are seriously expecting a senior level rails dev to do all that AND take additional duties with c++? cpp could mean a billion different things"

Them: "well this is a big opportunity that will increase your level to senior position"

Me: the add ALREADY asks for a senior position, why are you making it sound that I will get build towards that level if you are already off the bat asking for seniors only to begin with?

Them: You are not getting it, it is an opportunity to grow into a senior, applicants right now are junior to mid-level

ME: You are all not making any sense, please don't contact me again.

=======

Them: We are looking for someone with 15 years experience with Swift development for mobile and web

Me: What is up with your people not making these requirements in paper? if I knew from the beginning that you people think that Swift is 15 years old I would have never agreed to this "interview"

Them: If you are not interested in that then might we offer this one for someone with 10 years experience as a full stack TypeScript developer.

Me: No, again, check your dates, this is insulting.

===

* For another Rails position

Them: How good are you with Ruby on Rails in terms of Python?

Me: excuse me? Python has nothing to do with Ruby on Rails.

Her (recruiter was a woman) * with a tone of superiority: I have it here that Python is the primary technology that accompanies Rails development.

Me (thinking this was a joke) : What do you think the RUBY part of Ruby on Rails is for? and what does "accompanies Rails development" even means?

Her: Well if you are not interested in using Rails with Python then maybe you can tell us about your experience in using Javascript as the main scripting platform for Rails.

Me: This is a joke, goodbye.

====

To be fair this was years ago when I still didn't know better and test the recruiters during the email part of being contacted. Now a days I feel sorry for everyone since I just say no without even bothering. This is a meme all on itself which no one has ever bothered to review and correct in years for now. I don't know why recruiters don't google themselves to see what people think of their "profession" in order to become better.

I've even had the Java/Javascript stupidity thrown at me by a local company. For that one it was someone from their very same HR department doing the rectuiter, their shop foreman was a friend of the family, did him the service of calling him to let him know that his HR was never going to land the kind of developer they were looking for with the retarded questions they had and sent him a detailed email concerning the correct information they needed for their JAVAscript job which they kept confusing with Java (for some reason in the context of Spring, they literally wanted nothing with Spring, they wanted some junior to do animations and shit like that on their company's website, which was in php, Java was nowhere in this equation)

I think people in web development get the short end of the stick when it comes to retarded recruiters more than anywhere else.

Arrived today!
I'm using C++ for machine learning purposes using TensorFlow and OpenCV (rip Python, you are too slow 😭)

What are you using C++ for? 😁

C++ has become cockpit of Boeing 747
Too many controls? Yes.
Takes shitton of time to get ball rolling? Yes.
You need just bunch of them to get stuff done? Hell yes.
You still have to learn a lot of them if you plan to become professional? Yes.
You need to touch most of the fancy stuff only once in a while? Yes.
Many controls you wont be touching except once or twice in your whole career? Hell fucking yes.
You need those fancy controls when shit goes tits up? You better have them, or you are dead!
Creds: A.M.

Remember the super duper company I applied for? (Last rant)

Well, I did their coding challenge. And after many years I had to do a metric crapton of C++. It's not a fun language. It's frustrating how human-unfriendly it is, and maybe one reason why I low-key like it.

Anyways, here's hoping that I didn't fuck up too much.

On a side note, I realized tensorflow actually has a cpp api. I think I'm gonna work with that in my next mental breakdown. 🧐

"Sooo, children of the village, what are we going to write front-end in?" - I said to my infant students.
"Typescript with ts-loader/awesometypescript loader for webpack" - simultaneously yelled the kids.
"Exactly! Brilliant! And now, what are we going to be writing back-end in?" - asked I then.
The kids yelled: "PHP 7.2 with Laravel, or Go with Gingonic and juliensmith/httprouter, or Typescript without loader, with express/koa"
Truly stunned with their excellence, I asked "Well, now you 100% ain't gonna get it right - what are we going to be writing a desktop application that doesn't require a lot of native functionality and preferably, cross-platform in?" And the kids didn't hesitate to yell happily "Typescript targeting Electron", which has only brought tear to my eye.
"A native ms windows app?" "WPF under C#"
"A native gtk app?" "Vala"
"A native KDE/XFCE app?" "Cpp/Qt"
"A native mac app?" "Swift3.2/4"
I was in tears, just thinking about what future these kids have, but suddenly I have noticed one of kids seemed puzzled. It was Pajeet, an indian guy, ugh, his mom was a bitch. I asked him "What is wrong, little acoustic?" "But I like Java, and I would like to make back-end with Tomcat!" he replied. "Ooooh :3" cutely I moaned, trying to reach the handle of the table locker "I've got something just for you". I pulled out a rope, with sewed-in spikes, covered in drool and piss, came up to Pajeet and tenderly put it around his neck, making a knot. Pajeet fell under the table, and I got fired.

I had a coworker that was an Air Force pilot (99% certain he was telling the truth as I was working for a government contractor and he had security clearance so I'd be a little surprised if he fooled HR and our whole team). Thing is... He genuinely believed the earth is flat. Whenever anybody would ask "haven't you seen the curvature of the earth? Like... More than once?" He'd respond with "yes I have, what's your point?". Uh.... Okay.

Didn't help that he also was convinced cpp is the only language you ever need for any project. Like, "what if instead of building a web API and two separate native mobile app frontends (Swift/Java)... We instead build our own proprietary C++ framework that somehow runs on IOS and Android and we can also use it for our Backend instead of .Net?"

I'm not saying I love Java or Swift or that at some point I haven't thought about why we can't just use cpp in both, but you're supposed to grow out of that kind of thinking. I think every noobie or college students thinks "oh there's got to be a way". But at some point in your career you realize even if you could, it wouldn't be any easier to use and the performance gain would crazy small compared to amount of effort and you'd be playing catch up with both IOS/Android forever.

But no matter how many times we'd shoot it down, he'd keep bringing it up. And he wasn't straight out of school or something. He had like 20 years of programming experience.

I don't have a lot of memorable co-workers that were positive but honestly I think that's because usually if they're good at what they do I don't have to interact with them a bunch or spend time thinking "Jesus what am I going to have to fix next from this guy". I definitely have worked with good/great programmers, they just don't stand out as much as the shitty ones.

Seeing anything serious written in cpp with in line assembly, that level of witchcraft fascinates me

The year is 2019.

C++ is still one of the most powerful programming languages around..............with no centralized package manager that is widely adopted by the community that allows one to sandbox libraries from conflicts with one another.

I ain't hating, just find this funny and I love cpp

Apt get/git submodules it is!!

I can't figure out shit..
To be honest I created this profile just so I can write down somewhere what I am going through.
So, once upon a time I had graduated from college and went right into a corporate (has only been 2 years since). I was fortunate enough that I got assigned a project that was just starting, and even though I had no clue what was going on, I started doing whatever was assigned.
I initially worked in java and then finished all my tasks earlier than expected, so they switched me to another C++ project that builds on top of it.
Fast forward 2.5 years, I'm now the team lead of the CPP project and all my friends who were in the core team have left the company.
As usual, the reason behind it is shitty management. These mfs won't hire competent people and WILL ABSOLUTELY NOT retain the ones that are. I can feel it in my bones that it is time for me to leave, but fuck me if I understand what I am good at.
I have been able to handle all the tasks that they threw at me, be it java or c++ - just because I love logic and algorithms. I have been dabbling in ML and AI since 4-5 years now, but could never go into it full time.
Now I'm looking at the job postings and Jesus Christ these bitches do not understand what they want. I have to be expert in 34567389 technologies, mastering each of whom (by mastering I mean become proficient in) would need at least 6-8 months if not more, all with 82146867+ years of experience in them.
I don't know if I am supposed to learn on Java (so spring boot and stuff) or I'm supposed to do c++ or I'm gonna go with Python or should I learn web dev or database management or what.
I like all of these things, and would likely enjoy working in each of these, but for fucks sake my cv doesn't show this and most of the bitch ass recruiter portals keep putting my cv in the bin.
Yeah...
If you have read so far, here's a picture of a cat and a dog.

Why are children in tree data structure sad?

Because they only have single parent.

Why is starting a C++ project so overly complicated and annoying?!

So many different compilers. So many ways to organize the files. So many inconsistencies between Linux and Windows. So many outdated/lacking tutorials. So many small problems.

Why is there almost no good C++ IDEs? Why is Visual Studio so bizarre? Why are the CMake official tutorials literally wrong? Why can't we have a standard way to share binaries? Why can't we have a standard way to structure project folders? Why is the linker so annoying to use?

Don't get me wrong, I quite like the language and I love how fast it is (one of the main reasons I decided to use it for my project, which is a game almost comparable to Factorio)... But why is simply starting to write code such a hassle?

I've been programming in Java for years and oh god I miss it so much. JARs are amazing. Packages are amazing. The JDK is amazing. Everything is standardized, even variable names.

I'm so tempted to make this game in Java...

But I can't. I would have a garbage collector in the way of its performance...

R3post !!!

personalproject C++ codebase:
- Clean code,
- 1 class per file,
- naming conventions
- comments .
- No more than 10 files per folder

Work C++ codebase:
- 22 classes per file.
- Classname not the same as file name
- weird variable names CmdStng
- All files in one source folder.
- Source control from 20 years ago

Me every time I cannot find anything I wondering why it is in a different file on line 3574 inside another class with an unrelated filename

Couldn't stop laughing... :')

int********

I had a genuine respect for C++ developers back in 2001

Then this whole STL thing happened. Then C++11, C++14....C++17

Me now: Bitch do they even write code 🤣🤣

I might be fucked up, but I have a tendency to gravitate towards the shit that everyone else dislikes for the sake of knowing if their bias against is actually because shit is truly fucked up or if shit is legit plain WRONG.

From all technologies that I have worked with professionally I can count:

Java(currently in the form of old JSP services for an "enterprise level application")

Java for Android development - i was the lead engineer for a mobile project

Swift with IOS dev, same gig as the above.

C++ for Android development in the form of OpenCV with Java as well.

Javascript in all possible forms, basic input validation, ajax services, jquery datatables, jquery animations and builders.

Css/sass heavily

Clojure for an ldap active directory application

Python for glue scripts

Classic ASP with JScript and VBScript

VB Net forms

C# For ASP.NET MVC

Bootstrap for multiple intranet frontends

Node+Express for a logistics warehouse management tool

Ruby on Rails freelancing small gigs

Php in all ways possible from complete standalone php apps to Laravel and just php+composer apps aaaaall the way to wordpress

Django consulting

I have found that the one that I dislike the most is wordpress. And the one that I like working with the most is Node. Don't know why, i just do really fucking like messing around with Javascript, the language has changed a fuckload throughout the years and continues to increase and change. It was my first scripting language following a stint in me trying to learn cpp way when i was starting and royally FAILING

Never really got the hate for it, even when I used JScript with classic ASP i just enjoy working with Javascript a lil too much. And from all the above mentioned stacks safe from Php is the one, or one of the ones in which i don't royally suck :V

Refactoring 😜

I can't take a (C++) project seriously if it is using Visual Studio's build system instead of autotools, CMake or even just a Makefile.

Messed Up my first Coding Interview and that too of Google!

My first rant.

The first question was not an easy one. I cracked it though. Happy. Very Happy! I had 40 minutes left for the second question. And then came the nightmare. Okay, my foolishness.

I compiled my code. Compilation error.
Declared variables. Compilation Error!
Imported Libraries. Compilation Error!
Changed vector to an array. compilation Error!
Checked the loop for edge cases. Compilation Error!
Cannot use an IDE too. Tab's change is not allowed.

My score was still ZERO and I had only 15 minutes left.

Then lazily my eyes went to the language selected. It was C. I wrote the code in C++.

I mean HOW CAN I BE SOOOO STUPID??
I was coding in an entirely different language!

But..But, the story doesn't end here.
Next, I copied the code and switched languages. NOOO, my code was lost. I couldn't paste my code!!

I checked the timer- 5 minutes left.
Somehow, I managed to rewrite the code. And submitted it at the last minute.

I have no idea what will be the results. I just solved 1/2 questions.

SAD but FRUSTRATED at my stupidity :(

Lels

Before I was unceremoniously laid off by a shit company in which they tried to blame shit on me I was working on a opencv implementation of a proprietary document scanner.

I finished the Android prototype and was working on the ios implementation. It was left unfinished in the ios version because I was building it in swift and obj c to compare code bases.

They launched a shit unfinished Android app of their product without the scanner (they could not add the scanner lels) and have not been able to do shit on the ios version.

I did not give them the Android prototype. There was no binding contract that specified that what I developed was theirs. There is no record of anything.

The scanner? Is still in my phone and I still have the built project in my mac.
Unless them cheap assholes decide to pay another engineer for the opencv implementation, their vbscript php non theory knowing shit lead will have to figure out the required mat obj c swift java cpp code needed to build it.

Top kek

Our programing teacher(CPP) is so fucking bad at teaching.

I'm pretty sure his classes actually cause permanent damage, by rendering the other students unable to learn programing properly.

Whenever a sentence starts like, "For the advanced around you...", you can cough bullshit from the top of your lungs, because what he's about to tell is first semester c-basics.

*tries learning cpp after python*

My code all the time: we don't do that here

<rant>
I fucking HATE the Arduino environment right now.

First of all: you can't fucking put your project files in a sub folder to the main file. I can't write #include "src/motor.hpp" because it doesn't fucking know what that means.
Turns out you have to put all your header files in the fucking library folder common for all Arduino projects!

Secondly, you can't call your cpp headers hpp, they HAVE to be called h, or the Arduino environment throws a fit and begins whining about being unable to find the fucking files.
Not just that! You can't reference other Arduino libraries from within your library because the environment doesn't know what that means either.
To get around that you need to fucking include the library in your main file, AND THEN you can include it in the library file that uses it. After all, it should be the programmer's job to soon feed a so called IDE, right?

I'M SO FUCKING DONE WITH THIS SHIT! 😤

I'm ready to either program the Arduino directly with an AVR programmer or even port the entire project to the raspberry pi where I have a proper fucking Linux environment with a proper fucking directory structure so I can code proper fucking C++.
Hell I'm even fucking willing to spend all weekend porting all the code myself if necessary.

It's not reasonable that correct fucking C++ code is invalidated because I called the files something "wrong" and put them in the "wrong" directory.
</rant>

"user friendly project board" my ass

Bit the bullet and installed VS and relevant compilers for C++ and started fucking around with sdl.

Not as terrible as I thought it was going to be.
Pointers seem pretty intuitive. Apparently my time with python has not in fact mentally mutilated me.

When you want to run your cpp code for your customer

I was confused tbh lol 😂😂

I came to know and use C++ for 10 years now and I've just seen this syntax:

for(int i{0}; i<5; i++) { }

WTF is this shit??

My pronouns are C/C++

I am honestly surprised in how many different ways C++, VS, and libraries are able to fail over and over and over again.

Fuck you C++ libraries
Especially fuck Visual freeze Studio

C++ code written before current standards still complies and is just as maintainable, but every so often a new major change to the standard happens and I feel like all my code I wrote before last month or so now needs updated. "Range-based for" ALL THE THINGS. except I'm just retouching code and possibly adding bugs along the way.

Sometimes I just feel that my most mastered and beloved language suffers from a severe case of multiple personality disorder. As soon as I get to know it, it's suddenly somebody else.

Back when I was still in school for comp sci we had an advanced software engineering and design class with c++. At this time, everyone was expected to be proficient enough with cpp to go ahead and properly work with whatever the instructor would throw at us. And pretty much everyone was since past classes included a lot of c++ development. Of course, efficient at least related to academic studies rather than actual real world development.

Our teacher would mix in a lot pf phyisics and mathematics into what we were doing, something that I greatly enjoyed, while at the same time putting real world value concerning cpp best practices to avoid common pitfalls in the development of said language. Since most bugs seemed to be memory based he would be particularly strict about that.

One classmate, good friend and an actual proper developer now a days would ALWAYS forget to free his resources...ALWAYS for whatever fucking reason he would just ignore that shit, regardless of how much the instructor would make a point on it.

At one point during class on a virtual lecture the dude literally addressed a couple of students but when he got to my boy in particular he said: "you are the reason why people are praying to Mozilla and Hoare to release Rust as fast as possible into a suitable alternative to high performant code in C++, WHY won't you pay attention to how you deal with memory management?"

And it stuck with me. I merely a recreational cpp dev, most of my profesional work is done on web development, so I cannot attest to all the additional unsafe code that people encounter in the wild when dealing with cpp on a professional level.

But in terms of them common criticisms of C and C++ for which memory is so important to work with, wouldn't you guys say that it comes more from the side of people just not knowing what they are doing rather than a fault on the language itself?

I see the merits and beauty of Rust, I truly do, it is a fantastic language, with a standardized build system and a lot of good design put into it. But I can't really fathom it being the cpp killer, if anything, the real cpp killers are bad devs that just don't know what they are doing or miss shit.

What do y'all ninjas think?

I have noticed that C/C++ developers that deal with backend server technologies are very much likely to resort to PHP for some reason. I have noticed it from serveral developer friends of mine or simply by noticing how the topic comes along sometimes on web discussion forums.

I believe this is the reason why certain extension codebases that deal with php are(for the most part) exclusively done in C++, take Phalcon, written as an extension in C or PHP Swoole, which is written in cpp iirc.

I wonder what attributes does the language, or the tech stack as a whole has that would make this particular kind of developers feel attracted to the platform. Is it that is easy and widely available and they just say "fuck it, I don't wanna spend too much time in this shit" <--- which is a very valid point really.

Or them just having an innate preference towards it?

The Psychology Behind Developers: By Dr AleCx04

Why the heck would you allow (or need) nested block comments? Imo this is a major design flaw in the kotlin linter.

I always use /*... //*/ so I can remove the comment starter w/o having to remove the comment end, but kotlin just starts a second, nested comment there.

Java, C, Cpp, C#, JS,... Not one of these uses nested block comments. I think jetbrains was just lazy?

I mean, I know why such stuff happens. I also developed DSLs in MPS, but there sure are ways to go around such things..

Accurate af

First programming-course at the new school.
I was pretty excited until it hit me.
This is an intro-course.
We need to use CPP, not C.
We need to use Windows.
We need to use a shitty IDE instead of editor and compiler.
Went from super excited, to fuck this shit, pretty fast

I believe it is really useful because all of the elements of discipline and perseverance that are required to be effective in the workforce will be tested in one way or another by a higher learning institution. Getting my degree made me little more tolerant of other people and the idea of working with others, it also exposed me to a lot of topics that I was otherwise uninterested and ended up loving. For example, prior to going into uni I was a firm believer that I could and was going to learn all regarding web dev by maaaaaself without the need of a school. I wasn't wrong. And most of you wouldn't be wrong. Buuuuuut what I didn't know is how interesting compiler design was, how systems level development was etc etc. School exposed me to many topics that would have taken me time to get to them otherwise and not just on CS, but on many other fields.

I honestly believe that deciding to NOT go to school and perpetuating the idea that school is not needed in the field of software development ultimately harms our field by making it look like a trade.

Pffft you don't need to pay Johnny his $50dllrs an hour rate! They don't need school to learn that shit! Anyone can do it give him 9.50 and call it a day!<------- that is shit i have heard before.

I also believe that it is funny that people tend to believe that the idea of self learning will put you above and beyond a graduate as if the notion of self learning was sort of a mutually exclusive deal. I mean, congrats on learning about if statements man! I had to spend time out of class self learning discrete math and relearning everything regarding calculus and literally every math topic under the sun(my CS degree was very math oriented) while simultaneously applying those concepts in mathematica, r, python ,Java and cpp as well as making sure our shit lil OS emulation(in C why thank you) worked! Oh and what's that? We have that for next week?

Mind you, I did this while I was already being employed as a web and mobile developer.

Which btw, make sure you don't go to a shit school. ;) it does help in regards to learning the goood shit.

c or c++?
Why?

Lets hope this coveffe is loyalty

they say "you can do anything on C++"

I can't even initialize an array with a random length

I love working doing tasks like moving boxes.
Move 10 boxes from point A to point B. Simple, you know what to do. and you know when you are finished.

I Hate tasks such as: Change this Icon to other icon. (C++) Because it takes me 3 fucking hours to find in code where the fuck this happens! And every time my first instinct when I don't know something is go to the internet and search for it. But in this case I CaN't!.

Wife: asking why I'm browsing the internet looking at memes.

Because I Don't Know where the fuck I need to be to finish my task! And I am stuck in this repeating loop of searching in code, looking at memes and being ashamed of myself that I did not this fucking simple task in like 10 minutes.

And after 3 hours of doing basically NOTHING. I don't dare to ask a colleague about everything.

Please send help....

C++ development will be my end.

The absolutely unreadable errors, the overly convoluted macros set up in the project, the cmake build system.... The absolutely unnecessary separation into cpp and header files...

So I decided to switch over to Ubuntu to get used to it and have fun with it along with trying to use Vim just as a side thing for experience (I'm still studying anyways and its semester break).

So I setup Linux in an external disk, booted Ubuntu, setup everything and then loaded a side project coded in C++ and Allegro into Ubuntu.

A few hours of googling and trying to setup Allegro to be properly installed and understanding how to use GCC with Allegro, it finally found the library and one of the cpp files gave an error that is not "cannot find allegro.h". That's great!

Added all the other additional cpp files into the command and added all the includes and there goes the terminal lit up with errors ;_; I'm so tempted to ditch everything and go back to Visual Studios

My boss keeps pushing me to do „any“ courses..
I’d say I’m doing my job exceptionally well. In fact he even told me before he promoted me.

I had to tell him what I wanna learn in the next 2-3 years. I told him I wanna be decent in C++ because i love the language and in my opinion every dev can improve by learning a low level language.

Have some MITx courses and stuff I wanna do (I actually want to do them) but he keeps pushing me to send him the courses so he can push me and (I think) Monitor my progress..

C/Cpp and asm have always been my love, I wanna improve and learn. But I wanna do it for myself, not for my boss. The company doesn’t have any use for it anyway..

And those courses are 4 weeks to 12 months with scheduled assessments.

I shouldn’t have mentioned it. Now it’s an expectation they have.

Now I have to force myself into doing those courses in time.. on a schedule..?

90% of then will bore the shit out of me cause I already know it and the remaining 10% are stuff I wanna look at when I feel like it. But I don’t have a paper that says I know those 90% so yeah..

Why can’t he just be happy with the work I do during working hours and leave my free time up to me???

What are the chances that you get busted by your manager and 3 team leaders you personally know when you are going to a job interview?

We have poor men’s silicon valley near universities. Our company’s one office moves to another university. By the one in a million luck, interview takes at the same building where our next office of my current company will be. Managers and team leaders are there to inspect the new office. I enter the building, see them near elevator. One of them see me, with panic i wave my hand to him. There is a distance of ten meters, I hide behind a column. The team leader who sees me waving thinks I am with them to inspect new office. He asks others why am I not coming with them as I learn later. I can not pretend to play along and catch up with them, due to panic and time of interview is soon already. They get into elevator and finally I dont have to hide anymore 😂.

I got into interview and c++ exam with that physcology. Little did they knew that I just completed CPP PRIMER book. I both rock interview and exam but lets see if they will return with a job offer. What a rollercoaster of emotions.
Note: I am on mobile now so can not give more juicy details for now, fingers are tired.

Ok c++ professionals out there, I need your opinion on this:
I've only written c++ as a hobby and never in a professional capacity. That other day I noticed that we have a new c++ de developer at the office of which my first impression wasn't the greatest. He started off with complaining about having to help people out a lot (which is very odd as he was brought in to support one of our other developers who isn't as well versed in c++). This triggered me slightly and I decided to look into some of the PRs this guy was reviewing (to see what kind of stuff he had to support with and if it warranted his complaints).

It turns out it was the usual beginner mistakes of overusing raw pointers/deletes and things like not using various other STL containers. I noticed a couple of other issues in the PR that I thought should be addressed early in the projects life cycle, such as perhaps introduce a PCH as a lot of system header includes we're sprinkled everywhere to which our new c++ developer replies "what is pch?". I of course reply what it is and it's use, but I still get the impression that he's never heard of this concept. He also had opinions that we should always use shared_ptr as both return and argument types for any public api method that returns or takes a pointer. This is a real-time audio app, so I countered that with "maybe it's not always a good idea as it will introduce overhead due to the number of times certain methods are called and also might introduce ABI compability issues as its a public api.". Essentially my point was "let's be pragmatic and not religiously enforce certain things".

Does this sound alarming to any of you professional c++ developers or am I just being silly here?

A colleague is walking me trough some of the source code because we try to fix an issue.

colleague: Oh we don't use this anymore
Me: ...
LATER
colleague: This part we should refactor someday
Me: ...
LATER
colleague: Oh I think this is old code and does not exist anymore.
Me: .. .. ...

Great Colleague BTW :)
PS: fix will be posted Later.

Last year, we had computers architecture class where we study about the architecture of processors like RISC, CISC, SIMD... The teacher was a nice person but didn't have much knowledge on the field. I read some of Patterson&Hennessey book (computer organisation and design iirc) and learned how to use openmp and mpi, and then in the last lab we were required to optimize matrix multiplication using 4 threads in openmp, the best students optimiseed for 4 times at best, meanwhile I made 16 times optimisation and showed the teacher how fast it was. She was really impressed lol

I hate programming tutorials for a complicated language like c++ that are dedicated to absolute beginners of programming. If you've never coded before, why are you trying to learn c++?

Yo I heard you like compiling C/Cpp so we make you compile and link each individual file so you need a makefile for compiling everything. But that shit still gets to annoying to maintain so you make the make files with cmake. Just so you can compile a library basically at all.
And dont get me started on autoconf and random configure scripts you have to run before you actually configure shit.
Can we make compiling a regualr program any more difficult so that we need a whole ass A4 page of documentation just to end up with a binary of something?

That's why I love the new cpp Mc launcher XD

How many of you are agree with what is depicted in picture?

Holy shiiittttt I finally got 64bit NASM working on windows with cmake. Cmake documentation is fkn bad man.

I’ve got a c++ file that calls a procedure in an assembly file that calls win32 APIs to show dialogs and other cool shit. Compiling was working fine, linking turned out to be a bit of a pain in the ass, but figuring out how to enable NASM in cmake was a nightmare. Why is the cmake docs so horrific 🥺

Greatest language of all times is still C. It stood against the test of time. Any new language including Rust can hope to ba barely performant than C with too much overload.(I know most cpp abstractions if more efficient handwritten C equivalent but still).

Language is small, simple, elegant.

Getting back to the cpp applet I started somewhat recently (Vanilla + Gentoo kernel version checker)...

Me: "debugging c plus plus code"
Dictation: "f***ing c++ code"
...
Well, it's not too far off.

That moment you find your C++ code from 2012 but you still feel like you know nothing after 8+ years coding. 😭
(Impostor syndrome is strong with this one! 😂)

Most of us have scary stories about professors that think that they know about what they are talking about when it comes to teaching comp sci subjects. Shit is so backwards in most parts of the world with teachers showing outdated or completely pointless tech.

A friend called me the other day asking for classic ASP help because it was being used in his web class. Another was asking me about flipping c cgi web scripting. Wtf are schools teaching? Having the drive to LEARN actuall useful topics that are relevant on the market is hard enough as it is...shouldn't schools help at least a little bit? I was lucky, we were thaught Java, Python, cpp, js, sql, html5, css3, php, ruby and we had classes for node (for those interested) and asp.net mvc. Those were RELEVANT and good classes and while some outdated tech was good the rest is just bullshit. Specially since most teachers have 0 market value as develpers...but hey!! Wtf do I know! Of course my word is shit against all them doctorate and master degrees.

Gimme a break. School can be great. But a lot of the leadership there is toxic af for our industry. And while I appreciate the effort in me being thaught modern languages (and thaught is a hard word since I already knew how to program way before going to school) i still remember a teacher taking points away from an assignment for not using switch statements in Python...despite my explaining that there was no such thing (you can go around it by using a lil technique using functions, its pretty cool..pero no mames)
Or what about the time I mentioned to a fellow student how he could use markup for having more control with his windows forms while the very same teacher contradicted me saying that shit was not possible. Or the guy at the school in which I work teaching intro to programming using fucking vba...fk man if you are going the BASIC route at least teach them b4j or something fuuuuck.

I had good teachers, but they were always cast asside by dptmnt heads as if they knew better. I just hate pendejo teachers I really do.

I like rants that are thought provoking and push a message forward regardless of whether they may sting a little, so for my first post on here I'd like to hit at home with many of you.
Html5 "Native" Applications are not needed. Let's cover mobile first of all, the misconception that apps are written in either javascript or Native android/ Native ios environment. Or even some third party paid tools like xamarin is quite strange to me. OpenGL ES is on both IOS and Android there is no difference. It's quite easy to write once run everywhere but with native performance and not having to jump through js when it's not needed. Personally I never want to see html or css if I'm working on a mobile app or desktop. Which brings me to desktop, I can't begin to describe how unthought out an electron app is. Memory usage, storage space for embedding chromium, web views gained at the expense of literally everything else, cross platform desktop development has been around for decades, openGL is everywhere enough said. Finally what about targeting browser if your writing a native app for mobile and desktop let's say in c++ and it's not in javascript how can it turn back into javascript, well luckily c++ has emscripten which does that simply put, or you could be using a cross complier language like haxe which is what I use. It benefits with type safety, while exporting both c++ and javascript code. Conclusion in reality I see the appeal to the js ecosystem it's large filled with big companies trying to make js cross development stronger every day. However development in my mind should be a series of choices, choices that are invisible don't help anyone, regardless of the popularity of the choice, or the skill required.

Fuck you c++...!!!
TL;DR:
float a = 1.0/10.0;
float b = a*10.0;
a == b returns false
😐

Story:
A beginner of c++ here
Wrote about a 1000 lines code (spread across multiple files, m not dumb)
Passed 90% of cases
Took one and a half days to figure out what's wrong

Turns out c++ doesn't give accurate (as perceived by a human who thinks in decimal) results when comparing equality of 2 floats with ==

Shouldn't that be the first thing to be taught in schools?

Me: I may think in binary but you are the only 1
Her: huh?!?🤨

I am a chinese dev with 5-6 years experience, working on c/cpp/golang for backend server and PHP for web.

But I still feel hard to learn JAVA and JAVA web framework. You know it just has too many bultshit too learn, which is meanless to me.

Do you no-chinese guys also think so?

Couldn't be arsed with all the conditional compilation that angelscript required, so I dumped right back to good ol' lua for now.

Got lua in, vm started, loading strings and pushing/popping the stack.

Got SDL actually drawing as intended.

I don't know even half of what I'm doing.
Apparently header files that end in ".hpp" are specific to c++, while .h are for c headers.

I like the new SDL2 though, little bit different than SDL1. Not a lot of tutorials cover the difference, but I could kinda suss out from the documentation where I needed to adapt, even though I'm still pretty loose on the library, on the docs, and on c++ itself.

Still just a learning project.

Also, I'm continually surprised there isn't a portable, platform independent tool or little language just for replacing all pseudo-languages out there like .bat and .sh, and .zsh

Maybe even just a tool that standardizes it all, then takes config files that map the new standard to system dependant commands, so you can download the damn thing, configure the relevant environment variables, drop in the platform dependent configuration (or your browser or package tool detects what platform you are on and chooses the relevant package/download for your platform), write a console script and the tool automatically translates, and emits the system-relevant commands to that platform's console (so you don't even need much platform-specific code to do things like file access).

Every time I check my old codes i start insulting my self..... How the fuck was i that stupid..... Still Stupid tho but i m progressing :D

I m learning to code by myself without any instructor :').... I wanna use unreal engine but i forgot how to code with cpp since i m only using C# now.. made winform apps and installing xamarin to learn about cross platform devloppment :)

OK, here goes nothing: now, I absolutely hate putting the main function at the end of the file and everything else above it.

How do you do java style oop with classes and inheritance and all that in c++?
Do I really have to make a header and a source file for each class?

And while we are on it: are there any sources of "famous" games written in cpp?

C++: an octopus made by nailing extra legs onto a dog.

Guys does any of you know good first c++ project. I have a lot of experience with java and python so I am not new to programming, but I want to get proficient in C++ because I am soon starting a job which all lower level programming.

Got VS running, SDL up and running and outputting, and angelscript included. Only getting linker errors on angel at the moment, not on inclusion, but on calling engine initialization.
Who knows what it is. Devs recommended precompiling but I wanted to compile with the project rather than as a dll (maybe I'm doing something stupid though, too new to know).

Goal is to do for sdl, cpp, and angelscript, what LOVE2d did for lua. Maybe half baked, and more just an experiment to learn and see if I can.

Would be cool to script in cpp without having to fuck with compilers and IDEs.

As simple as 1. write c++, 2. script is compiled on load, 3. have immediate access to sdl in the same language that the documentation and core bindings are written for.

Maybe make something a little more batteries-included than what lua and love offer out of the box, barebones editors and tooling and the like, but thats off in the near future and just a notion rather than a solid plan.

Needed to take a break from coding my game and here I am..experimenting with more code.

Something is wrong with me.

I'm thinking about what language to dive into next.
I already have a pretty good knowledge of Go and mediocre knowledge of C and Java.

So far I thought about...
1. CPP, as I need it for school and it runs on literally anything.
2. Rust, as is seems to spread and the combination of low-level, memory-safety and abstraction seems pretty appealing to me.
3. Kotlin, specifically kotlin-native, is it combines java-like high-level programming with native speed.
4. Nim, as it combines high-level techniques with c-like freedom.

What do you people recommended, or something completely else?

LOL XCode....I think they meant "X"tra useless, resembling such as a bag of dicks without handles!!!!

Also, being fucking buried because there's aren't any devs anywhere to be found near me makes me extra cranky!
Ive been hammering away at this Flutter, Java, Swift, Python, and Google maps for just about 36 hours on 3.5 hrs sleep. I just can't stop, I fuckin love this shit!!!
Considering the fact that I'm self taught and just started writing code for real about 7 months ago, I'd say I'm handling this alright for now. Every bit of tech is getting shot out of a cannon at this one- maps, real time tracking, state level auth/Id verification, custom components like ID scans/native desktop applications on custom linux machines, body cams, SIP trunking... all in 3 apps which are 100% multi-platform and scaled up to high end enterprise levels and being groomed for national release. I'm writing the code and doing the tech for ALL of it- even down to custom painted barcode scanners, a wallet system built from scratch, GPS integration, location/geofence based document querying... holy fuck guys I'm gonna fuckin die haha!!!
I went from barely getting websites made in late summer to this very moment, where I am pumping shit out in Flutter, Dart, Python, CPP, Js, Swift, Java, Kotlin, Obj-C, SQL/noSQL, and who knows what else.
I don't even know what the hell I just said haha I hope everyone has a great day!

I am new to c and cpp.
I used to exploit my college's competitive programming platform cus it had a bad architecture and almost no auth checks.
For every ajax request, they weren't sending auth tokens or any form of identification and ran all the programs without any logs and on the main thread and as root.. wtf, right?
But recently they've changed something to the site and I cannot run bash commands using system() call.
Is there any other way to execute bash commands using c and cpp.
I already configured a miner in their server but then they re-deployed it cos someone forked bomb the shit out of it.
I'm a noob in c and cpp btw!

After 12h coding cpp continuously ....

been exploring the options for cross platform desktop app, and i found :
java : both awt and swing look ugly, i really like OOP of java, and the way projects are organized is easy to scale, but i need to deploy the jdk, and the speed on gui apps isn't that great
C# : (.net/ mono, i can't grasp F# and vb is stupid) looks native on windows, not so much alien on both linux/mac, and being a java cousin is a pro, i found the Eto library for mono even looks more native on *ix than winforms
wxwidgets: for C/C++ so far this looks like the best option for total native feel and performance, but man i fucking hate C code, and this looks a lot like C code, even with proper native Cpp support, maybe i should dive deeper in it
GTK+ : did any one mention C code ? because this mother fucker is plain C with macros all over the place, it made me realize why wx is promoted as Cpp friendly, i doubt I'll use this
tcl/tk : even tho ive never wrote a single line of tcl in my life, the tk lib is the default ui for both python and ruby on all supported platforms,
and i really love ruby, and Python is Usually a joy to work with
Qt : this by far looks like the best option, proper OOP in C++, bindings for python (ruby binds are outdated), almost native look and feel on supported platforms, and even has a gui builder in xml or json/js (qml) however i bet I'll use such a thing, the building tho depends on an external preprocessor "moc" and some wicked macros, also makes working with templates a fucking mess, and the heavy dependence on QObject inheritance makes integrating external libraries a bit more tiring, the signal slot system makes more sense in python than in C++, since it makes me confused about the flow of the code
lazarus: is a freepascal implementation that looks and feels like delphi, not so much for native look and feel, but good performance and easy language to handle
electron : this fat mofo is fat, it's the slowest of all options, if i want an html app, I'll just compile a stripped down webkit and deploy that
what do you think ? and did i miss something ?

So today I tried to code in c++ by separating class code into header and cpp file which I had not done before. Compiler was throwing error while compiling, "undefined reference to std::cout". Took me nearly an hour to figure out I was using gcc instead of g++.

C++ development experience is absolute shit on Windows

Like using any IDE but VS (which is also shit cuz Micro$oft) to write anything in C++ is just absolute shit.

So… C++ seems kinda ok, as long as you don’t use like 80% of the language :-)

This is me making concessions when a library I really want to try (Dear ImGUI)is written in C++…

(yes, I know about cimgui, but for some reason I wanna learn upstream instead of generated bindings…)

So, I have a weird issue. I'm trying to finish my homework and the only thing that's stopping me is that for some reason VS is skipping a line of user input code. Can anyone help me understand why?

cout << "Make: ";
cin.getline((*c).make, 32);
//when debugging the the console skips this line of code. Trying to figure out the issue.

cout << "\n\nModel: ";
cin.getline((*c).model, 32);

Is there a simple CPP equivalent to a tree node in Java that has a parent and a arraylist of children? Or will I have to write out a 500+ line class to get the same functionality? 🤔

Can I build apps in Android devices using only C/C++ ? I mean is possible? I heard it is, but how that can be achieved? Can someone explain!

Bold of me to assume that a project that solely exists as an example on how to use a library would include said library in the download.

(In the project file structure already exists a folder for libraries and in it was a folder with the name of the library. And I of course didn't check if the [library name] folder contained any files)

__readfsdword(0x30) because getting the PEB is cool

Great practice/skill sharpening idea for my fellow mad dogs that like to get down in multiple languages/syntaxes:

Pick something simple that won't cause too much stress, but will make you sweat a little bit and put up a good fight, ha!!!

For example, I picked the classic "Caesars Cipher" and picked 5 languages to create it in! I picked Dart, Java, Python, CPP, and C. Each version does the same thing:
1. Asks for a message
2. Runs the logic
3. Prints the message cipher.
4. To decrypt, you just run the same program again and enter the cipher text at the message input prompt. The message gets deciphered using the same logic an shows up as the original text.

The kicker:
Only dox/books allowed for reference. Otherwise it wouldn't push you to get better!!!

Python, C, and CPP were EASY, even with me never having used C before. I am great at using Dart, and that one really challenged me for some reason, but I finally got it. The previous 3 langs took less than 40 lines of code each (with Python being only 18 I believe). Dart actually took somewhere around 50, and Java took about 371784784. (Much love to Java though for real!)

Kinda boring as shit, but I gotta tell you it felt fuckin GREAT to look at all 5 of those programs after completing them, no matter how barbaric... especially when you complete 1 or 2 in a language you've never used or maybe felt really challenged by. Simple exercises that hold a lot of important, relatable logic no matter the subject is our lifeblood!!!

Do people use cpp forms in Visual Studio? Or mainly just use forms for C#?

Couldn't they come up with a shorter name than reinterpret_cast? It makes lines of code so much longer if you have multiple casts in one line. 😥

To you CPP-devs,
I want to write a small ask-password tool, like systemd-ask-password, but tty-only and non-systemd.
I use termios to switch the terminal into noncanonical mode and disable echo of stdin.
Now I want to read chars from cin and append them to a string, until I read an endl or an error occurs.
In C, I could use an input-loop with getchar, but how could I do this the CPP-way, since cin.get() is nonblocking?

Ok so that's my plan, find a kernel with HUGE amout of drivers and , high version.

I built a small os based on linux
-- kernel version 5.0.2 from Plop Linux,
many libraries added 'by hand' -- packages from apts of Debian&Ubuntu, and unpacked packages into system with ArchiveManager,
has GUI but it's called xfree86 ( looks strange when a very old app running on Kernel5 )
So, without compiling, i can make a os.

But i found that Plop didn't compile rtl8188eu module which makes linux support some specific network cards.

I have no professional compiler but a tiny C/Cpp compiler called TinyCC (aka. tcc), but for my pc ( CPU freq = 800MHz ), it seems not possible to compile the module by myself.

And then i downloaded a 5.2 kernel with modules from kernel.ubuntu.com, but when i tried to mount my disk ( part. vfat ), i got some errors like IO charset not found, and then i replaced it with Xanmod kernel but also reported an error said Invalid Arguments, but i checked /proc/filesystems, it supports.

So what can i do? Are there any pre-compiled kernel & modules with 'full common supports'?

I tried kernel 4.4 ( from Ubuntu 16.04 LTS ) just now but the driver crashed when wpa_supplicant tried to initialize the device.

when you find a project you'd like to clone and learn about but you cant even get their examples to build locally...

yes im looking at YOU every c based project on github.

Getting used to C++.... Jesus those syntaxes.... you can write it so or so or this way... also this way.... did i mentioned this?!

!serious

Would you go with Rust or C/C++ to build Malware (rootkits, Ransomware kind) ? Why ? 🤔

Hello there I had a question in mind
I want to customize my telegram desktop client to filter some channel message for just my side
I mean I can delete certain channel message from my client so it doesn't show up in unread message
there are some channels that repost duplicate messages I want to write a filter to exclude them from my chat list

I'm familiar with CPP programming and I've worked with telegram api before.
But I don't know where to start on telegram open source desktop client to implement this feature
can you give me some hint to where should I look at?

Hey can someone tell me please that how to make y and n option in c++

Hey fellow c++ devs, i have a question. I am currently working for a company that has a system with more than 300 000 thousand lines of maintained code and it is written in C++03. A lot of it utilises boost and custom performance work arounds and migration is currently out of the question, but I would really love to see some Cpp11 sugar in the code-base. I know there might not be too much business value to this potential endevour, but what do you think?

Been using python for a couple years now. I've had brief ventures into Java and C# but they weren't for me. I've been looking into Cpp recently (watching cherno tutorials etc). Can anyone recommend a good written resource for learning?
