Will be attaching code for these 3 files:
CustomerDemo.cpp
Customer.cpp
Customer.h
Source code for CustomerDemo.cpp:
#include <iostream>

{
string response = "y";
double val;

Customer b("J", "101 Main St.", "Rockford", "IL", "61801", 100.00);
Customer c("Doe", "101 Main St.", "Rockford", "IL", "61801", 100.00);
Customer z("D", "101 Main St.", "Rockford", "IL", "61801", 100.00);
while ( response == "y" )
{
cout << "Purchase value (in $): ";
cin >> val;
if(!c.add_purchase(val)) break;;
cout << "Do you want to purchase another item (y/n)? ";
cin >> response;
}
cout << "Please pay the balance of $" << c.get_unpaid_balance() << endl;

system("pause");
return 0;
