Question

And Python code for the following programming problem and the pseudo code below

Write a modular program that will calculate the cost of purchasing a meal. The Python program can use global or local variables and RAPTOR use global variables. 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:
o Yum Yum Burger = .99
o Grease Yum Fries = .79
o 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? (Enter yes or no): no

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 1
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 ->2
Enter the number of fries you want 2
Do you want to end your order? (Enter yes or no): yes

The total price is $ 8.1832
Do you want to end program? (Enter no to process a new order): no

Enter 1 for Yum Yum Burger
Enter 2 for Grease Yum Fries
Enter 3 for Soda Yum
Enter now ->2
Enter the number of fries you want 2
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? (Enter yes or no): yes

The total price is $ 3.9856
Do you want to end program? (Enter no to process a new order): yes

The Pseudo code is:

Module main()

Call declareVariables(endProgram, endOrder, totalBurger, totalFry, totalSoda, total, tax, subtotal, option, burgerCount, fryCount, sodaCount)

//Loop to run program again
While endProgram == "no"

Call resetVariables(totalBurger, totalFry, totalSoda, total, tax, subtotal)
//Loop to take in order
While endOrder == "no"
Display "Enter 1 for Yum Yum Burger"
Display "Enter 2 for Grease Yum Fries"
Display "Enter 3 for Soda Yum"
Input option
If option == 1 Then
Call getBurger(totalBurger, burgerCount)
Else If option == 2 Then
Call getFry(totalFry, fryCount)
Else If option == 3 Then
Call getSoda(totalSoda, sodaCount)
End If

Display "Do you want to end your order? (Enter no to add more items: )"
Input endOrder
End While

Call calcTotal(burgerTotal, fryTotal, sodaTotal, total, subtotal, tax)
Call printReceipt(total)

Display "Do you want to end the program? (Enter no to process a new order)"
Input endProgram
End While

return totalFry

def getSoda():

global totalSoda

totalSoda +=sodaCount * 1.09

return totalSoda

def calcTotal():

global subtotal

subtotal += totalBurger + totalFry + totalSoda

global tax

tax += subtotal * .06

global total

total += subtotal + tax

return total

def printReceipt(total):

print("Your total is $",round(total, 2))

#Loop to run program again

while endProgram == "no":

resetVariables()

#Loop to take in order

while endOrder == "no":

print("Enter 1 for Yum Yum Burge\\Enter 2 for Grease Yum Fries\\Enter 3 for Soda Yum: \\")

option = int(input("Enter option: "))

if option == 1:

bugertotal = getBurger()

elif option == 2:

frytotal = getFry()

elif option == 3:

sodatotal = getSoda()

endOrder = input("Do you want to end your order? (Enter no to add more items): ")

mytotal = calcTotal()

printReceipt(mytotal)

endProgram = input("Do you want to end the program? (Enter no to process a new order): ")

Step-by-step explanation:

The python source code displays the menu of a restaurant and the prices of each meal. The module takes multiple orders, calculates and displays the total bill of the order with tax included.
