Should I learn C++, or C#?

Isn't it the same thing? /s

I learned C#.

Now, I’m a WordPress dev.

*sigh*

Learn C++.

As a c# dev.. please learn c++ and leave the idea of working for an m$ thing :)

Learn Lisp

I've briefly used both and I'd say C++ because it can be cross platform where you are stuck with windows if you use C#. C++ is also more challenging imo and that's what I prefer.

If you don't have any programming experience with c-like languages go with c# to start and then move to c++, if you are already good at java go with c++
Still c# is much faster (in terms of dev time) for simpler applications with its windows forms

Good old C and then maybe mix some ++ in it.

Learn how to code, not language.

C# all the way!

You should learn PHP
