can anyone confirm if this works?

Works in JS
Works in php
Probably works in a lot of langauges as EOL isn't bound by logical operators

Yes, tested with https://try.dot.net
if (1==1)
{
// empty
}
else;

Runs.

@rEaL-jOkEr Ah.. new account I see

Yes, this will probably run in most languages. It's the same thing as

while(condition);

A very common way of clearing a buffer is to do

while(buffer.read());

When the buffer is empty, it will return null, and the loop will end.

This is allowed because it (like most other control structures) looks for a single block of code after it's declared. That's why you can omit brackets when you only need a single statement after an if.

The brackets act as a single statement: a scope statement. You increase the depth of the scope and put code in it.

A blank statement is still a statement. So just ending the line with a semicolon should be allowed by most control structures in most languages

@bkwilliams what about

if (1 != 1)?

Does this run, too?

It will work.

This is not threat. You are basically telling the compiler, if you don't execute that 'if', there is nothing else I can do.
That's more like pleading

Wtf

@AlgoRythm I don’t know why I never understood why the input buffer would clear when throwing it in an if statement before. I always had the issue of clearing it until I read online that you could do that.
If(std::cin >> input)

Thanks for pointing out the obvious.....it was fucking scope all along lmao. Why didn’t I think of that? *smacks forehead*

It looks like quite a good code signature to use

I'm pretty sure compiler will ignore this (at least at C++)

Nowadays compilers are pretty smart and they will ignore useless code, and try to optimize other code
