Improved Taking a Restaurant Order Program.
Create a new version of the restaurant ordering program BELOW that uses lists to look up menu items, record the items ordered by the user, and print a full receipt. The following requirements:
a. Use a list to look up the names of the menu items; call this list menu_items. This list will replace the use of the multi-way condition. Create the list with the names of the menu items, in the order they appear in the program you created for Part X of Assignment Y. Notice that, because the first position in a list is zero (0), item number 1 in the menu is stored in menu_items[0].
b. Use a list to look up the prices of the menu items; call this list menu_prices. This list will also replace the use of a multi-way condition to obtain this information. Create the list with the prices of the menu items. Make sure this list aligns with the list in part (a) above. That is, for index value item_nro, the price in menu_prices[item_nro] corresponds to the dish in menu_item[item_nro].
c. Use a list to record the items ordered by the user; call this list ordered_items. This list contains the items’ menu numbers, not their names.
d. Use a list to record the quantity of each item ordered; call this list ordered_quantity. Make sure this list aligns with the ordered_items list. That is, for example, if the customer first orders 3 Cheese Sandwiches (item 7 in the menu), and then 2 Sodas (item 10), then ordered_items[0] is 6, ordered_quantity[0] is 3, ordered_items[1] is 9, and ordered_quantity[1] is 2.
e. After taking an order, the program prints a full receipt, listing the items ordered, quantities, and prices, together with subtotal, tax, tip, and grand total. You can look at a sample receipt from the restaurant you selected, or search online for “restaurant receipt,” for the overall layout of the receipt.
