The CSEE Book Store offers Computer Science textbooks that are required for courses as well as reference books. The store keeps track of the books in inventory with an inventory file. A student can use the order system to purchase single or multiple copies of the books available. The system creates an invoice for the student and also removes the books ordered from the inventory.
The Task
after printing a greeting to the user, presents the user with a list of the book titles available. The user can then see more information about one of the books on the list or quit. If the user chooses to see the information about a book, s/he is presented with the book's ISBN number, title, author, publisher, the price per copy and the number of copies in stock. The user will then enter the number of copies s/he wants to order (0 is a possibility).
Once the user has entered the number of copies to order, a line item is generated and written on the invoice and the inventory is decreased by that number of copies. The user is then presented with the list of titles again.
When the user has finished ordering books, the invoice is completed by adding the sales tax (5% of the subtotal) and writing the tax and total. A new inventory file is then produced which is exactly like the original inventory file but with the new numbers of copies adjusted to reflect the order.
