For the example under Friend Functions
How is the following true?
“Notice that neither in the declaration of duplicate() nor in its later use in main() have we considered duplicate a member of class CRectangle. It isn’t! It simply has access to its private and protected members without being a member.”
Duplicate is declared in the public section of CRectangle. How is it not a member function and set_values is?
Is this a good example? Any better ones if not?
Any function declared or defined as
friendinside a class is not a member of that class. It’s just a friend function.That said, if a friend function is also defined within the class, it will be found by ADL lookups involving that class (which is normally used for overloaded operators).
