Question

C++ Programming

Enum - Structure - Array

You are asked to develop software for HR department to calculate employee’s weekly salary. The program should contain the following information about a student by declaring a struct:

Name (string of characters)

       Employee ID (string of characters)

       Level (ENGINEER, MANGER, DIRECTOR)

       Hourly Rate (floating-point number)

       Working Hours (floating-point number)

       Weekly Salary (floating-point number)

Your program will read an employee data and print the information of employee’s Name, Employee ID, level, weekly salary, and gender. Program will perform to calculate each employee’s weekly salary and display all employee’s data. The program will be terminated when users enter “N” to discontinue entering information.

The calculation formula:

1. If employee is an engineer, working hours is less or equal 40 hours, his/her weekly pay will be hourly rate * working hours. If working hours is over 40 hours, the salary will be paid over time pay.

             Over time pay = hourly rate * (working hours - 40) * 1.15.

2. If employee is a manger, working hours is less or equal 40 hours, his/her weekly pay will be hourly rate * working hours. If working hours is over 40 hours, the salary will be paid over time pay.

             Over time pay = hourly rate * (working hours - 40) * 1.20

3. If employee is a director, working hours is less or equal 40 hours, his/her weekly pay will be hourly rate * working hours. If working hours is over 40 hours, the salary will be paid over time pay.

             Over time pay = hourly rate * (working hours - 40) * 1.3.

Test Data:

Name	Employee ID	Level	Hourly Rate	Working hours
Cindy	D001	Engineer	$30.57	40
Jeff	D002	Manager	$36.25	48
Tom	D003	Director	$40.05	42
