Question
Your task as a programmer is to create a menu driven program. Your program must-reads from already existing data file which contains the unknown number of records (max 100):
The record should consist of the following fields for each employee:
First Name
Last Name
Social Security Number
Gender (Male or Female)
Hours Worked
The salary should be calculated on the weekly basis of 40 hours. Any time over 40 hours worked, is considered to be overtime. When working overtime, employees get paid 1.5 of their normal salary. (For example: If an employee worked an hour overtime, and he was normally paid $20.00 per hour, his overtime would be calculated as $20.00 x 1.5 = $30.00)
The menu should contain the following choices:
1. List all employees to the screen with their salary.
2. Add an employee to the payroll.
3. Delete an employee from the payroll.
4. List all the female employees (Roses of the G-ds).
5. List all employees with overtime
6. Alphabetize the list of employees.
7. Who gets the highest salary.
8. Quit and Save.
Please note: If an employee is deleted from the database, he/she should no longer exist in the database, when the program is rerun.
Please comment your program adequately and name it 6.c(Points will be deducted if there are no comments, or the program is incorrectly named).
Note : you receive 20 more points if you do it dynamically (link list)
PLEASE ANSWER WITH C LANGUAGE, NOT C++ OR JAVA! WILL RATE PROPERLY
