Question

For my assignment I have to write a program that creates a restaurant billing system. I think that I got it correct but it says that it is incorrect, so I was wondering if someone would be able to look over my code. It says that I need tax of $0.20, and the amount due to be $4.10, which is what I have in my output.

My issue is that I have the correct outcome when I run my program but it doesn't seem to be counted with the program that I am working with. Could someone look at my code to see if I have any issues? I think that I got it correct but it says that it is incorrect. It says that I need tax of $0.20, and the amount due to be $4.10, which is what I have in my output. I might be able to get it to work if I can get my output which is currently Tax $ 0.20, and $ 4.10 into $0.20 and $4.10, but I am not sure what I would need to do in order to remove the spaces that I am getting in my code.

Here is my assignment.

Write a program to help a local restaurant automate its breakfast billing system. The program should do the following:

Show the customer the different breakfast items offered by the restaurant. Allow the customer to select more than one item from the menu. Calculate and print the bill. Assume that the restaurant offers the following breakfast items (the price of each item is shown to the right of the item):

food Price Plain Egg $1.45 Bacon and Egg $2.45 Muffin $0.99 French Toast $1.99 Fruit Basket $2.49 Cereal $0.69 Coffee $0.50 Tea $0.75 Use an array menuList of type menuItemType, as defined in Programming Exercise 3. Your program must contain at least the following functions:

Function getData: This function loads the data into the array menuList. Function showMenu: This function shows the different items offered by the restaurant and tells the user how to select the items. Function printCheck: This function calculates and prints the check. (Note that the billing amount should include a 5% tax.) 

Here is my code:

    getData(menuList, size);
    showMenu(menuList, size);
    printCheck(menuList, size);
