Question
Your task as a programmer is to create a menu driven program. Your program must-reads from already existing data file data.txt which contains the unknown number of records.
You may think of record as struct in C:
Define Employee as struct with the following field:
First Name
Last Name
Gender
Social Security
Age
Hours Worked
Rate
A pointer to Employee
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)
Since you have unknown number of records in Data.txt file. You must create
A link list.
Your Menu should allow the user to add, delete, print, sort by last name and
Save the result of operation into file name result.txt.
Sample
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.
5. List all employees with overtime.
8. Quit and Save.
Extra Credit: provide necessary functions to allow two employee of opposite
Sex to get married or divorce. Also function to print married people with their
Spouse first name.
