// Homework #6
// Problem 2.17
//
// Develop a C++ program that will determine if a department store customer
// has exceeded the credit limit on a charge account. For each, customer, the
// following facts are available:
//
//    a.) Account number (integer)
//		b.) Balance at the beginning of the month
//    c.) Total of all items charged by this customer this month
//    d.) Total of all credits applied to this customer's account this month
//    e.) Allowed credit limit.
//
// The program should input each of these facts, calculate the new balance
// ( = beginning balance + charges - credits), and determine if the new balance
// exceeds the customer's credit limit. For those customers whose credit limit
// is exceeded, the program should display the customer's account number,
// credit limit, new balance, and the message "Credit limit exceeded."
//
