Pizza App Prototype Development

This document outlines the requirements for a pizza app prototype development project. The project involves creating a mobile application that allows users to select pizza sizes, add toppings, and calculate the total order cost. The prototype should include features for handling multiple pizza orders, adding additional items like drinks, and calculating taxes. The project emphasizes the use of functions to organize the code, including functions for displaying menus, calculating pizza costs, adding additional items, calculating total order costs, and handling payment methods. The project also requires the creation of a hierarchy chart to illustrate the relationships between the functions.

Pizza App Prototype
Step 1
The employee is asked to enter the pizza size which are, small, medium, and large
The following message will be displayed at the screen.
Enter pizza size (s/m/l):
Step 2
The following menu will be displayed on the screen:
Add topping (enter to stop)
1:Pepperoni, 2:Ham, 3:Pineapple, 4:Anchovies, 5:Peppers
6:Sweet Corn, 7:Sausage, 8:Mushrooms, 9 extra cheese:
The employee will be able to include the topping desired by the customer by entering the
number for the topping. The user will be able to include multiple toppings then press enter to
stop and continue with next step.
Step 3
The following message will be displayed on the screen asking for the customer address.
Enter Delivery Address: What if the customer wants to eat in or wait and take out?
The employee will be able to enter the customer address and continue to the following step by
pressing enter.
Step 5
The program will calculate the total price. Will this include additional items such as drinks or
deserts or salads? Will you have a subtotal for the pizza cost, a subtotal for additional items, the
tax, the total order cost?
Features to be added:
Multiple pizza order, add a soda, add toppings, and calculate taxes. These should already be
added to the program at this prototype stage. How will you handle payment, cash/credit?
All of the above needs to be broken into FUNCTIONS, with a function to display a menu, a
function to calculate pizza cost, a functions to add additional items, a function to calculate total

order functions to handle method of payment. The flowchart below looks fancy but a hierarchy
chart better displays use of functions. In my comments to your fist submission I gave you
information on using hierarchy chart. Please follow that for the next demonstration assignment
submission. The hierarchy chart is to include all the function descending from function main
and shown in the textbook.
