Question

C++ Language: 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. Additional requirements: The program should allow the user to make repeated requests until they choose to exit The program should find multiple matches if necessary The program should have options to print out both a full list and a list that just includes Name and Phone Number The program should use at least two struct types and one enumerated type
