The restaurant only has four items on the menu. You may pick what those items are and set prices for them (each item must have a different price). You need to keep a running total of what is ordered and keep looping until the cash register operator asks the program to print out the total bill. Also, you need to keep track of how many of each item are purchased and display them in the final bill. Be creative with the name of your restaurant, what sorts of food your restaurant offers, and what the prices are (ie, make up your own... don't just copy mine!).
Here is an example of what your menu might look like. The formatting does not need to be exactly like this, but all dollar amounts must be formatted to 2 decimal places.
The Hamburger Shack ------------------------------- A. Hamburger $1.00 B. Cheeseburger $1.20 C. Double Cheeseburger $2.40 D. Bacon Cheeseburger $2.00 Current Subtotal: $0.00 Enter your selection -->
At this point, the cash register operator might press "A" (or, s/he might press "a". Your program should do the same thing either way). You should add the cost of item A to the running subtotal and ask the operator if they are ready to print the final bill (the operator will enter "Y", "y", "N", or "n" as an answer). If the operator is not ready to print the bill yet, redisplay the menu with the updated subtotal:
Enter your selection --> A New subtotal is $1.00 Would you like to print the bill now (Y or N)? N The Hamburger Shack ------------------------------- [...print your choices again...] Current Subtotal: $1.00 Enter your selection -->
When the operator says that, yes, s/he would like to print out a final bill, your program should print out an itemized list of what was ordered (and the total cost for each item), the subtotal, the sales tax (use 5% for sales tax), and the total (subtotal + sales tax). For example:
[...] Would you like to print the bill now (Y or N)? Y Customer Bill ------------- 1 Hamburger $1.00 2 Cheeseburger $2.40 1 Bacon Cheeseburger $2.00 ------ Subtotal $5.40 Sales Tax $0.27 ====== Amount Due $5.67
Notice that two cheeseburgers were ordered in this example, so the cost is listed as 2 times $1.20, or $2.40. Also notice that since no double cheeseburgers were ordered, they are not mentioned on the bill (it does not say "0 Double Cheeseburger"). The program should stop executing after the final bill is printed.
