    why private virtual function?

    Hello everyone,


    Why do we need to fine a virtual function as private? As special functions we can achieve and any special limitaitons?


    thanks in advance,
    George

    Maybe restrict the usage of a specific virtual function for a said derived class?

    This has been answered elsewhere.

    Why do you ask at least 3 questions in a row in multiple threads per day?

    Thanks Elysia,


    What you mentioned below is dealing with private function (I agree), but anything special for private virtual function?

    You already got your question answered, didn't you? In another forum?
