Lab 5.5 Programming Challenge 1 Yum Yum Burger Joint
Write the Flowchart for the following programming problem and the pseudocode below.
A restaurant wants you to write a program that will calculate the cost of purchasing a meal. This program will include decisions and loops. Details of the program are as follows:
· Your menu items only include the following food with accompanied price:
· Yum Yum Burger = .99
· Grease Yum Fries = .79
· Soda Yum = 1.09
· Allow the user of the program to purchase any quantity of these items on one order.
· Allow the user of the program to purchase one or more types of these items on one order.
· After the order is placed, calculate total and add a 6% sales tax.
· Print to the screen a receipt showing the total purchase price.
Your sample output might look as follows:
Enter 1 for Yum Yum Burger Enter 2 for Grease Yum Fries Enter 3 for Soda Yum Enter now ->1 Enter the number of burgers you want 3 Do you want to end your order? (Enter yes or no): no Enter 1 for Yum Yum Burger Enter 2 for Grease Yum Fries Enter 3 for Soda Yum Enter now ->3 Enter the number of sodas you want 2 Do you want to end your order?
