This problem is related $($and modified$)$ to Problem $8$ Cash Register and problem $5$ Retailitem

Class of Chapter $10.$

Part a: Write a class named Retailltem that holds data about six items in a retail grocery store.

The items are Bread$(24$ oz$),$ Milk$(1$ gallon$),$ Eggs$($one dozen large$),$ Butter$(1$ lb$),$ Cheese $(8$ oz$),$

Ham$(8$ oz$).$

Then write a class called CashRegister$6.$ There are only six items in this hypothetical store.

The purpose of the program is to prepare the bill for any customer that comes to the cash

register. This class uses Rerailltem class.

If a customer says that he$/$she is purchasing $2$ breads, $2$ gallons of milk, one butter and one

ham, then the cashregister program should calculate the bill and present it to the customer.

Use a GUI to ask the customer for the items and how many the customer wishes to purchase.

Then the bill should be prepared and presented to the customer with the total bill the

customer needs to pay.

You see, this is a model for any kind of grocery store with say, $10000$ items or $100$ items or

any number of items on its shelves.

part b: Prepare a dictionary of $20$ items called item $1,$ item $2,...$ item $100$ with random prices

between $$1$ and $$10($cents are permitted. Then prepare a new CashRegister$20$ class. This

program also should present the bill to the customer with the total bill.

Be creative and the printed bill should look neat and presentable. Give a name to your grocery

store.
