C$++$

The Student class defines the strings studentName and studentSSN as protected data members. A constructor has arguments that initialize the data. The class StudentAthlete is derived from the Student class and has a private member variable studentSport, which describes the sport the student plays. Both classes have a member function, identity$().$ The base class Student outputs the student information in the form:

student: studentName SSN: studentSSN

The identity$()$ function in the base class should support polymorphism and should be overridden in the derived class to add the information $-$ Sport: studentSport. Finally, the class StudentWorker is also derived from the Student class and includes the data member studentDept, which describes the department where the student works. The identity$()$ function for this class should report the student name, the student's social security number, and the department where the student works.

Define these three classes and write a test program that creates an array of one Student object, one StudentAthlete object, and one StudentWorker object. In a loop, execute the identity$()$ function for each object so that the information for each object is displayed.
