int& func(int& a);
i keep seeing it in my book and it assumes you already know what it does, so it must be something basic. What does it do?
ahh, crap, i actually already understood the pass by reference idea, i just got it mixed up with the return type syntax. sorry about that.
let me ask a different question:
what type of variable is returned with a int& return type?
you said it was returning a reference but not a pointer?
