Question

11.11 LAB: Warm up: Online shopping cart

(1) Build the ItemToPurchase class with the following specifications:

• Attributes (6 pts)
• item_name (string)
• item_price (float)
• item_quantity (int)
• Default constructor (2 pt)
• Initializes item's name = "none", item's price = 0, item's quantity = 0
• Method
• print_item_cost()

Ex. of print_item_cost() output:

Bottled Water 10 @ $1 = $10

(2) In the main section of your code, prompt the user for two items and create two objects of the ItemToPurchase class. (4 pts)

Ex:

Item 1
Enter the item name:
Chocolate Chips
Enter the item price:
3
Enter the item quantity:
1

Item 2
Enter the item name:
Bottled Water
Enter the item price:
1
Enter the item quantity:
10

(3) Add the costs of the two items together and output the total cost. (4 pts)

Ex:

TOTAL COST
Chocolate Chips 1 @ $3 = $3
Bottled Water 10 @ $1 = $10

Total: $13
