Question

Develop a program, in which you'll design a class that holds the following personal data: name, address, age, and phone number. As part of the program, you'll then create appropriate accessor and mutator methods. Also, set up three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information.

Input:

• data for the following attributes of 3 instances of the  Personal Information Class:
• name, address, age, and phone number

NOTE: The input data do not need to be real data; they need to be entered at the keyboard, when program is run.

Processing: Develop the following:

• Personal Information Class
• A program that creates three instances of the above class

Output:

Set up a loop and display data within each object:

• name, address, age, and phone number
