How to access protected method in base class from derived class?

Question

Here is a sample of code that annoys me:

class Base {
  protected:
    virtual void foo() = 0;
};

class Derived : public Base {
  private:
    Base *b; /* I         


        

Answer 1

How do you access to the protected overrided function?

--- from where?

You can access a protected member only via inheritance (apart from the methods of the same class). Say for example you have a class Derived1 which inherits from Derived, then objects of Derived1 can call foo().

EDIT: MSDN article on protected access specifier.
