Thank you for your response.  Actually, it's not the new() that is causing
me problems.  Let me present the problem in another way.


    class A;  // forward reference

    class B
    {
        int print()
        {

        }

        foo(A* a)
        {
            cout << a->print();  // compiler error here
        }
    }

    class A
    {
        int print()
        {

        }

        bar(B* b)
        {
            cout << b->print();
        }
    }

    main()
    {
        a = new A;
        b = new B;

        b->foo(a);
        a->bar(b);
    }


Basically, I have two objects that are dependent on each other.  I thought
I
would be okay as long as I use pointers to these objects.  Is there a way
around this problem (other than re-designing)?
