Create a program that will ask the user for number of chicken wings or wings they want to order at a restaurant. The number of wings and the sauce will determine if there is a discount on the total wings purchased. For hot wings purchased in a quantity of 6 or less there is no discount. For hot wings and a quantity of more than 6 but less than or equal to 12, there is a 10% discount. For hot wings purchased in the amount of greater than 12 but less than 24 the discount is 20%. For sweet and sour wings, purchased with a quantity of 6 or less the discount is 5%. For sweet and sour wings and a quantity of greater than 6 but less than or equal to 12, the discount is 10%. For sweet and sour wings purchased with a quantity greater than 12 but less than or equal to 24, the discount is 15%. For all wing purchases greater than 24 wings, the discount is 25%. All wings are 50 cents each.
The program needs to ask the user for the type of wing either hot or sweet with the following prompt:
Enter the wing type:
The program also needs to ask for the quantity of wings using the following prompt:
Enter the quantity:
The program needs to determine the discount rate, calculate the subtotal, discount and total cost of the wings. It then needs to print out all of these values using the following text:
Discount Rate:
Subtotal:
Discount:
Total:
Finally the program needs to ask the user if they want to purchase another order of wings using the following prompt:
Enter yes to add another order of wings
