Hey guys, I have an assignment that I have been working on for hours and I've done a lot of testing and I finally got it working, but when I try to change it to make sure to prompt the user for an input I can't get it to work correctly.

Assignment is Below:

For this assignment, you will write a C/C++ program to print out information from the Premiere database.

You are to report on the most recent order for a particular salesrep. Prompt the user to enter a salesrep number. For that salesrep’s latest order, print the order number, date, customer number, name and address, and a list of items ordered. For each item, list the item number, description, number ordered, unit price and total amount for the item (number ordered*unit price). After all of the items are listed, print out the total amount owed for the order (add up all of the total amounts for the order).

I'm just so fustrated I can get it to work correctly.
