Your Supermarket Coupons – The Grocery Bill
Understand the Application
Each supermarket wants your repeat business. To learn exactly how much, you can start by looking at the value of coupons that stand to be awarded by your local market. For example, say your grocery bill usually is between $10 and $60 dollars. Let’s say for today that it is $20. That means for spending $20 today your market will entice your return visit by offering you a discount coupon that can be applied to your next grocery shopping bill. Of course, in order to encourage increased grocery spending the amount of the discount awarded will be based on the amount of groceries purchased.
The Program Spec
Your program will prompt the user for the cost of their groceries.
Then you are to calculate the value of the coupon to be awarded based on the amount of the grocery bill.
Use the table below to determine coupon amounts.

Input Error Checking: Since we have not yet covered loops you can assume that when it is time for the user to enter a number to represent the amount of his/her day’s grocery bill that a valid numeric value will be typed in. You do not need to test for non-numeric nor negative values. Note: A numeric 0 input is a valid data entry.
Here are some other requirements:
Create constants versus using literals in your source code.
Use a float to represent both the shopper’s grocery bill as well as the coupon amount.
Format the discount coupon amount to 2 decimal places (Example: $19.20).
Show me at least five different runs, supplying five different sets of values that the user enters each time. Have each run demonstrate one of the five coupon percentages awarded.
Here is a sample run (remember you’ll need at least five runs):
…
Please enter the cost of your groceries: 160.01
