C++ Program to inherit two classes Student and Faculty from the base class Person
a. In the base class two functions input( ) and display( ) to input the data members of class Person.
b. In the derived classes two functions input( ) and display() to input the data members of classes Faculty and Student.
c. Create the objects of the three classes and call the functions.
