Can Derived Class Access Private Members Of Base Class?

How do you access base class private data in the derived class?

You can directly access the private member via its address in memory.

Can private members of a base class are inheritable?

With private inheritance, public and protected member of the base class become private members of the derived class. That means the methods of the base class do not become the public interface of the derived object. However, they can be used inside the member functions of the derived class.

Which type of members can’t be accessed in derived classes of a base class?
