Using C++, you need to design, implement, and test a grocery shopping list program. The program should maintain and display a list of items.

You will design an Item class. The class should have data elements for the following information: item name, unit (i.e. can, box, pound, or ounce), quantity to buy, and unit price.

Consider following things: do you need any functions other than the constructor? How do you calculate the extended price for the item (quantity to buy times unit price)? How do you print it to the screen?

You will also need a List class. You will store Item objects in your List object. When you enter a new item, an Item object must be created and added to the List object.

Use a dynamic array to hold the Item objects. The dynamic array should start with a capacity of 4 Item objects. Do you need a print function in this class? Think about it.

Your program must perform the following activities: create a list, add items, remove items, and display the shopping list. To add an item, you should prompt the user to enter the name, unit, quantity to buy, and the unit price.

The display should show: each item name in the list, item unit, the quantity to buy, the unit price, the extended price for each item, and the total price for all items. Oregon doesn't have a sales tax so you can ignore that. Debug and test your program.

Once you have the List and Item classes working correctly, test if an item is already in your List before adding it. Overload the == operator to perform the test. There is a simple example to overload this operator in the book. Keep it simple.

How will you compare items? You can assume that the user will type the information correctly and compare them by the item names.
