Question

Language: C++ I need a working code that can do this so I can expand on it.

1. Write a program that will manage a simple address book. The program should allow you to view and search existing entires as well as add new entries. The data should be stored in a file structured so that a person's first name, last name, and phone number are stored on one line separated by commas and the next line has their address. (Fully documented program in separated .cpp and .h files)

Additional requirements:

The program should allow the user to make repeated requests until they choose to exit

The program should show multiple matches if present

The program should have an option to print out a list that just includes Name and Phone Number

The program should use at least two struct types and one enumerated type
