++

I've been using this command, but I'm not exactly sure what it does.
What I assumed it to be is, say:

x = x+1;

where x is an integer. Is this correct?

Yes. ++ means add one. That is where C++ got its name. The maker of it thought he just added one thing to C, so he called it C++. You can also use -- to subtract one (I think).

Ah thanks. And yes, you can use -- for subtract one.
