Expand your application to include an EVALUATE button. Each time the EVALUATE button is selected, the sales representative data will be read and the amounts sold in SUPPLIES, BOOKS, and PAPER will be totaled. If the amount sold on all three categories is greater than or equal to (>=) $8,000, write the sales representative data to a new file, stars.txt. These sales representatives will receive a bonus to demonstrate appreciation for a job well done. Your stars.txt file should not be opened for appending each time the application is run.
