Description: In the chapter, we stated, “When a base-class member is inappropriate for a derived class, that member can be overridden
in the derived class with an appropriate implementation.” If this is done, does the derived-class-is-a-base-class-object relationship
still hold? Explain your answer.
ANS: No. The “is a” relationship assumes that everything belongs to the base class object belongs to the derived class
object and also assumes that all functionality of the base class is present in the derived class object.
