    vector with pointers to objects?

    Hi, Im trying to create at vector of objects... the vector should contain objects from B and C.

    Code:
    class A
    {
    // code
    }
    
    class B:A
    {
    // code
    }
    
    class C:A
    {
    //
    }
    so my Q is do I need to create a pointer vector of Obj A?

    Can I create class A like:
    Code:
    class A
    {
      vector <A *> aVec;
    }
    and fill it with objects of B and C from main()? ITC how?

    If you want to make use of polymorphism, then yes, though you should prefer a vector of smart pointers, or a Boost ptr_vector instead.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
