Week 5 Lab— Fireworks Stand Checkout

Scenario

Your algorithm will keep track of a customer’s purchases at the local fireworks stand. Customers will not know exactly how many items they will purchase, so using a For loop on this lab is not allowed. Let’s keep the rules simple. 

·         Accept the dollar value of each item purchased from the user until the user is finished. 

·         When purchases are complete, enter a sentinel value of -1 (indicating that the user has finished). 

·         If the item purchased is $50.00 or more, give your customer a 10% discount on the item purchased. 

·         Display the purchase to the customer with the original price and the discount price.

·         Loop up and ask for the next item’s price (-1 to stop).

·         Display the Grand Total after the loop terminates

Enter price (-1 to stop):  20

Item original cost: 20
Item discounted cost:  20

Enter price (-1 to stop):  50

Item original cost: 50
Item discounted cost:  45     (10% discount!)

Enter price (-1 to stop):  -1

Grand Total:  65

Be sure to think about the logic and design first (IPO chart, pseudocode, and flowchart), then code the C# program.
