Problem
Your city library has hired you on a consulting basis to provide them with an application to calculate overdue charges. The overdue charges apply to hardcover or paperback books, records, tapes, CDs, and videos. The librarians want an easy way to calculate the overdue charges, keeping in mind that a borrower could be returning multiple overdue items. Some method of looping to enter the next item is necessary. The total number of overdue items and the total amount due should display.
