Question

Please use C++，thank you！

Write an AddressBook class that manages a collection of Person objects. Use the Person class developed in question 2. An AddressBook will allow a person to add, delete, or search for a Perso n object in the address book The add method should add a person object to the address book. The delete method should remove the specified person object from the address book 0 .The search method that searches the address book for a specified person and prints the list of persons matching the specified criteria. The search can be done either by first name, last name, or person id. Write a main program class to test your AddressBook. Write a Person class that contains the following fields and methods: 2. First Name Last Name » ID Number .Necessary constructors. . Methods to return last name, first name, full name, and ID Number . Methods to print last name, first name, and ID Number Write a main program to test your class.
