Problem Statement You have been asked to write a program for a retail store that will allow them to calculate discounts for their employees when they buy items. Discounts are based on number of years worked as well as if the employee is a manager or hourly employee. They are also allowed no discount once they have received $200 in discounts for the year.

The code has been written in C

Explanation:

//input libraries fist, the code is in C

#include<stdio.h>

#include<string.h>

OUTPUT

Input number of Years Employed2

Input Totalal Previousious Purchases Before Discount3

Input Employee Status4

Input Days Purchase5

Employee Discount =0.100000

Employees YTD=0.300000

Employees Purchase Before Discount=3.000000

Employyes Discount Day = 199.199997

Employees Totalal Purchase=-194.199997
