Could someone explain to me (in layman's terms please) when to use pointers, pass by reference, this pointer and friendly functions. I understand the concepts but I can't think on my own when to use them. Can someone explain? thanks.

You would use pointers or references for two reasons: 1. You want to modify the actual parameter inside the function. 2. You want to avoid pass by copy to conserve resources when passing something big. If you are doing it for the second reason and not the first, then pass by reference-to-const or pointer-to-const.
