My program is structured as follows:
Classe.cpp // Implementing class methods
Classe.hpp // Class prototypes
Main.cpp // Main file
In my file Classe.hpp I have the prototype a friend function:
friend int mdc(int, int);
The implementation of this function is in Main.hpp , the question here is: how can I use this function in my file Classe.cpp ?
I tried using the this-> e:
Was not declared in this scope
I searched, but the questions I encountered dealt with other aspects of friend functions, and I was strongly advised not to implement such a function within my class. How can I accomplish this?
