I need the below requirements added to my code. Any help would be appreciated.
The local frozen yogurt shop you wrote the program for in Topic would like you to modify the program to handle an extended menu.
? In addition to frozen yogurt, the store has added ice cream to the menu. o Yogurt will now cost:
? 0.44 per ounce, if amount purchased is less than 10 oz
? 0.41 per ounce, if the amount purchased is 10 or more oz o Ice cream will cost:
? 0.51 per ounce, if amount purchased is less than 10 oz
? 0.47 per ounce, if the amount purchased is 10 or more oz
? The container options have also been expanded. Single servings may be purchased in: o a plastic cup for free o a sugar cone for an additional $0.25 o a waffle cone for an additional $0.50 o a souvenir bowl for an additional $0.75
? Customers may still optionally add toppings to their frozen treats with new pricing: o $0.50 per topping for 1 – 2 toppings o $0.45 per topping for 3 – 4 toppings o $0.40 per topping for more than 4 toppings
? Since the discount is now built into the cost per ounce, the discount will no longer be computed separately.
