It is to make a cash register.
This is the criteria:
***Requirements for the cash register case study.***

Your program should produce the following:

1. Display the following screens:

a. Offered Menu with its price. (Maximum of 10 menus ONLY)

b. Summary of order displaying the total amount and the payment of costumer.

c. Actual receipt displayed on screen.

2. Computes the appropriate tax and tax exceptions for senior citizen, total amount to be paid by the customer and change.

3. Program will only terminate when the user answers YES if asks to exit the program.

I am very thankful to someone who will help me.

A program is just a collection of functions. You write the functions one at a time.

For example, there is a tax calculation. Do that one first. It needs an argument for the purchase price and returns the tax.

Next, write the receipt function. It needs arguments for the purchase price, the tax and the change. This function displays the receipt on the screen. This is a display function so it should do calculations, like figuring out the change.

AT this point write a main() that calls these two functions with hard-coded values for the arguments so you can check that they work.

Next, write the purchase function. It needs argument for he purchase price, the customer's money. The function calls the tax function to get the tax and then calculates the total purchase. Then it calculates the change and then calls the receipt function to display the receipt on the screen.

This is the core of the cash register. The other items, like the menu of things to buy, can be added later after the purchase function is written and tested.

Post again when you have this part working.
