A few things i never quite found the answers for:
what does return do. I never really understood when something should return (1); or return (0);
if you call a function, that say does a quick calculation, but doesnt pass anything back to the function taht called it, should it return 1 or 0?
Is C language obselete? University is teaching us C, but why not C++? Its difficult in C to do things like basic graphics, etc, would you ever nowadays write a commercial program in C??
