Re: very intersting:derived class private member accessed???

They are accessed via the base-class pointer. They are public in the
base class, therefore when using the base as interface (or accessing
them via base pointer), they should be public. Accessing them through
the derived pointer, this would not work.

class Base
{
  public:
    virtual void v1() = 0;
};
class Derived
{
  public:
  // ...constructor etc.
  private:
     //Note: v1 not private when accessed through baseclass reference
or pointer!
    virtual void v1()
    {
      //...some code
    };
}

Base* bp( new Derived() );
Derived* dp( new Derived() );

bp->v1(); //Ok, as public when accessed through base ptr
dp->v1(); //Error - private!


You weren't using the derived pointer in your example, you were using
the base


Use #include <cstdio> over here...

Kind regards,
