    A) Why not make the function global?

    B) Look up the friend declaration. I think it might help you.

    Unless it is static, the only way it can be accessed is if a whateverclass example is declared. Such as:


    Code:
    class a
    {public:
       void func(){cout<<"a class function";};
    };
    
    
    int main()
    {a dog;//has to be declared to access func
     dog.func();
     return 0;
    }

    If it's a derived Class, and you'd like to implicitly call the function of one of it's classes, check out the :: Operator

    ex.

    CLASS_X:ISPLAY();


    p.s.

    Friend Functions prove that your code isn't logically structured.
