Write a C program and submit the source code, along with multiple test cases as screenshots for the following problem:

A software company sells a package that retails for $99. Quantity discounts are given according to the following table:

Quantity Discount

10-19 20%

20-49 30%

50-99 40%

100 or more 50%

Design a program that asks the user to enter the number of packages purchases. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount.
