The local t-shirt shop sells shirts that retail for $14.99. Quantity discounts are given as follow:

Number of Shirts Discount
< 10 0%
11-20 10%
21-50 15%
51 or more 20%


Write  a program that can run within a .cpp file that prompts the  user  for the  number of shirts  required and then computes the total price. Make sure the program accepts only nonnegative input.

  • You must use a constant to represent price of the shirt
  • You must use the correct data types for your constants and variables
  • You must validate your input.  
    • Do not allow negative number of shirts. This should display a warning
  • You must use one or more if/else branches for your decisions
    • You must also use a logical operator at least once to check the ranges.
  • Your output should be formatted correctly
    • Prices should have two decimal places
    • Percents should have one decimal place
