Question

Your programming assignment in this Module has three parts. Follow the instructions below:

Create a class Person, which has a name, address, city, state, zip, and phone number. Create a default constructor to initialize the variables to some default values. DO NOT get them as an input from the user. If you prefer non-default constructors, then you can have them, but that is optional. Have a "display()" function to display the values.

Create a class Student, which inherits from Person, and has additionally grade, course, and GPA. Create a default constructor to initialize the three variables to some default values. DO NOT get them as an input from the user. If you prefer non-default constructors, then you can have them, but that is optional. Have a "display()" function to display the values. From the Student "display()" function call the Person "display()" function.

In the "main()", create an object of Person. Display its values. Then, create an object of Student. Display its values. This would display all the variables from both Person and Student.

Add plenty of narrative comments.

Your program must be compilable and executable.

Then add:

you created a program for a class Person and a class Student. Reuse those two classes for this assignment and build upon them as follows:

Add another class Professional that inherits the Person class and overrides the display() method.

Enhance all three classes to use Polymorphism on the display() method.

In the main() method, use a polymorphic pointer variable pIndividual of type Person to call the corresponding display()method of all the three classes.
