Review for a test help please :S
One of our review questions is the following:
Be able to describe how to overload an operator as a class member vs. a friend function, and when you cannot implement it as a class member.
I understand how to do this (code-wise) but not sure if I understand the principle.
My answer: You only overload a function as friend if i needs to access private members. Otherwise we make it a non friend member. Would this be a sufficient answer to the last part of this question??

no, that's incorrect.
A member function has access to the private members, there is no concept of non friend member.
