Thread: Need help with some basic C++

Your problem is on that line and your technique is wrong. Fix that line, and maybe the other spot, and make sure your code conforms to the C++ standard.

(Hint: Provide real information on what doesn't work and maybe someone will provide real solutions )

So if you can't show us what you're doing, how are we supposed to know how you're screwing up?

If you're lost on the basics of the language, start with a good tutorial or a good book and start learning the language. Also, I would recommend that you start learning how to write console programs, before GUI programs, since GUI programs usually demand a lot more knowledge of the language to be able to make them.

Class or Object? If class, you probably mean static members.

Code:

ClassName::memeber(<param>);

If object, you need to have a reference to that object to be able to use it's funtions.

Code:

class B
{
public:
   void member_of_B()
   {
        cout << "B here!\n";
   }
};



Class A
{

   B& b_ref;

public:
   A(const B& reference_to_B_object)
   :    b_ref(reference_to_B_object)
   {}

    void use_member_of_class_B()
    {
         b_ref.member_of_B();
    }

};



int main()
{

   B b;  // create B object
   A a(b); // create A object and pass it a reference to the object of class B from above
   a.use_member_of_class_B(); // A accesses a non-static  member of class B

    return 0;
}

or place A and B in a stronger (has-a) relation:

Code:

class B
{
public:
   void member_of_B()
   {
        cout << "B here!\n";
   }
};


Class A
{

   B b;

public:
   A()
   :    b()
   {}

    void use_member_of_class_B()
    {
         b.member_of_B();
    }

};




int main()
{

   A a; // create A object whose constructor creates a B object
   a.use_member_of_class_B(); // A accesses a non-static  member of class B

    return 0;
}
