Question

Create a class called AddressBook. It should be able to store a maximum of 50 names and 50 phone numbers (make an array of structures in the object or two arrays). It should contain a method called addName that will take a name and phone number and add it to the address book. There should be a method called findName that will take a string for the name and return the phone number if found in the list otherwise return “Person Not Found”. The class should have a method called display to show all the entries in the address book sorted by last name (last name, first name). Create a main function to test your class. Inside the main ask for five names and enter them into the address book. In the main, look for one that is in the address book and test for a name that is not in the address book. Finally, in the main, display the names in the address book.
