well,
it's a wonderfull tutorial on this site
but it isn't explained how to compile
can anyone explain it briefly
That would depend on your compiler, but from what I hear most of them just have a button or menu option somewhere that says "Compile" or "Debug."
Download Dev-C++ (for simplicity) or Visual C++ Express.
Create a new project. Place your code between int main() and return 0;
Go up to build, compile, or whatever it says and click build project/solution. Then run the executable.
which platform you are talking about?
