Thread: question about classes and functions

is their a way to call a class function within another class function?

A) Why not make the function global?

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

but if its a class function, isnt it already global?

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.
