I've been looking at examples and tutorials of code since I started getting into programming and I've noticed that when cout is used most more advanced programmers tend to use std::cout rather than just including cstdlib at the beginning of the file. Is cstdlib a c++ thing and mostly c programmers use std::cout? I mean I know it's not just cout but I see this a lot.
Oh, you know I was thinking it was the using namespace std; right after I posted this, but why do some programmers not use it then? I've seen many people just using the std::[call] a ton of times in their programs where they could have just used the using namespace std; to write less.
