Question

Your assignment is to create a restaurant ordering system where the cashier can create the menu and then take in the order and display the order back to the customer
Program Specifications Level 1 - Create a menu and make a 1 item order (max grade 60/100): a) User may enter any number of menu items. b) Once all the menu items are entered, the program will begin requesting to take the order of 1 item. c) You must ensure that the item they pick is in your menu items list. If it is not, they should be making a different choice. d) User may choose to run the whole program again once their selection is made. (Therefore, they create a new menu and take new order) e) Must use at minimum two methods: one to create the menu, the other to take the order f) Must use 1 single dimensional array, for the menu items Level 2 - Create a menu and be able to order multiple items (max grade 80/100): a) User may enter any number of menu items. b) Once all the menu items are entered the program will begin requesting to take the order and the customer must set how many items they are going to order. c) Once they have chosen the number of items they will order, next request what those items are. d) You must ensure that each item they choose is in your menu and if it is not, they should be making a different choice. e) User may choose to run the whole program again. (Therefore, they create a new menu and take new order.) f) Number and type of variables and methods is up to the student to determine.
