Haha. Think of a deck of cards. The base class represents the table where the cards will be used. The derived classes represent various actions with the deck of cards ( shuffling, dealing... ). One of the derived classes inparticular represents all the cards currently visible (face up) on the table. When a card is dicarded, I call a member function of my discards class to add the card to an internal array. I must also add the card to the list of visible cards. But rather than calling two functions, I want to know if I can automate this from the discard class by calling a member function of the visible class directly.

class second : public base
{
    void DoSomething()
    {
    	first *pFirst=new first();
        pFirst->DoSomethingElse(); // This calls a method of the first class
        // delete pFirst;
    	DoSomethingElse();
    }
}

Somethings seem HARD to do, until we know how to do them.

Is there some problem in declaring a pointer to the first class in the second one:

Is it at all possible for one class to call a function in another class?
