Do Programming you want fries with that? Due Date: Tuesday, October 12, 2004
PROJECT #2
You have been hired to put together a mock-up for the cash registers at the world-famous "Snarky Burger" fast food restaurant. Your cash register program will accept the following input: A letter code indicating what item on the menu the customer wishes to order. Accept both upper and lower case input. The choices are: A. B. C. D. E. Snarky burger Snarky fries Snarky soda Snarky Value Meal Snarky salad
Certain choices should lead to some follow-up questions (which are not asked if the customer is not ordering such an item), each of which should have a one-letter answer (and you must accept upper OR lower case make certain you tell the user what letter you are expecting, e.g. "Enter `Y' or `y' for Yes"): Snarky burger : Do you want cheese? Snarky fries : Large or small? Snarky Value Meal : Regular or Mega Super Size?
As it receives this input, the cash register needs to calculate the price of the purchase based on the following information: Food Snarky Burger Snarky fries Snarky soda Snarky Value Meal Snarky salad Option no cheese with cheese small large regular mega super size Price $0.80 $0.95 $0.75 $1.00 $1.70 $4.10 $5.00 $1.35
It should display each item and the price after it has been ordered: Snarky Burger with cheese $0.95
Extra Credit #1: Allow the user to "void" the most recent purchase and take it off.

After each item is ordered, have the cash register ask if the customer's order is complete. (Again, this should require a one-letter answer with upper or lower case both accepted.) If the order is not complete, the program should loop and ask for the next item. When the order is complete, the cash register must ask: Does the customer have a Frequent Snarker discount card? (Same rules about the answers as above.) The Frequent Snarker discount card gives a 10% discount.
If it is complete, the cash register needs to take the total cost of the order, figure out the discount if the person has a Frequent Snarker card, and report the final price. The cash register should then ask for the amount money of the customer hands to the Snarky employee. This amount can be typed in as the following format: 5.50 Extra Credit #2: If the customer offers less money than the price of his/her purchase, reject the payment, and keep asking for the total amount the customer hands over until the customer has actually paid for the purchases. The cash register then prints up a receipt with the following information: SUBTOTAL $4.29 Discount Card: 10% -$0.42 TOTAL: $3.87 --------------------------------------------Cash tendered: $5.00 Change: $1.13 Note that discount amounts can be rounded or truncated; it is your choice. Note also that if the customer did not present a Frequent Snarker card, no discount information should be mentioned at all on the receipt (it should go straight to the TOTAL): TOTAL: $4.29 --------------------------------------------Cash tendered: $5.00 Change: $1.13 All prices must have a dollar sign and the decimal point must line up. Here are the niddly details of the project: Write out an algorithm first as you did last time. Turn this in by Friday, October 1, in class. This will be part of your grade. Store the prices for each item using const variables.

Use a switch/case structure to handle the initial letter code input. You can choose which structures to use in...
