In summary, the effect of protected and private derivation is to elevate the effective status of member variables and member functions of the base class as viewed from the derived class:

• A protected derivation makes all the public member variables and member functions of the base class appear to be protected member variables and member functions.
• A private derivation makes all the public and protected member variables and member functions of the base class appear to be private member variables and member functions.
