// Tutorial 22: PhoneBook.cpp
// Stores and displays phone book entries using 
// overloaded operators
#include <iostream> // required to perform C++ stream I/O
#include <string>   // required to access string functions
#include <iomanip> // required for parameterized stream manipulators
#include "PhoneNumber.h" // PhoneNumber class definition

// function main begins program execution
int main()
{

   // define variables
   int count = 0; // stores the number of entries in the phone book
   int selection = 0; // stores the user's menu selection
