Supermarket project:

Project Description:

The project enables the user to enter a group of purposes, so that for each purpose the user enters his group code and the number of units from

The same purpose. When finished, the user enters an X instead of the purpose code.

A menu appears to the user containing several options.

Option No$.1$: Total invoice in shekels $($total item prices$)$

Option $2$ Total bill in dollars $($$$1=3\mathrm{.}5$ shekels$)$

Option $3$ Total discount in shekels $($total discount on all items$)$

Option $4$ Payment $($request to enter the amount paid and display the remaining amount as usual$)$

Option $5$ Offer the highest value and lowest price

Option $6$ Cancel the process and start over

Option $7$ Move to the next customer

Option $8$ Exit

Each item belongs to one of the following groups $($e$,$ d$,$ c$,$ b$,$ or a$)$ so that the unit price is according to the group and items

The unit price is $2$ shekels, b: $4$ shekels, c: $6$ shekels, d: $8$ shekels, e: $10$ shekels.

Regarding the discount, the customer gets a discount of $5\%$ if the total bill is more than $100$ shekels, and $10\%$ if the total is

The bill is more than $1000$

There is a $16\%$ tax on the value of purchases, calculated before the discount.

Notes:

o The form of the list must be according to what was mentioned and what is found in the experiment below.

o The solution method must be adhered to and the presence of five Functions as follows:

o The first function: costFinder is used to display the menu. It displays the list of options

o A second function: printMenu to calculate the price for each item. $($Price of the item $=$ number of units $*$ price of the group to which it belongs

Purpose by symbol$),$ the function takes the symbol of the group to which the purpose belongs and the number of units of the same purpose and calculates

Price for this purpose.

o A third function: shikelToDollar to convert the amount in shekels into dollars, so that the same function prints the result on the screen.

o A fourth function: discountCalculator, to calculate the discount value, takes the total amount and returns the discount value to the amount.

o A fifth function: remaining to calculate the remaining amount by taking the amount paid and requested and displaying the remaining amount
