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.
