Payroll Program for Abbas International

Abbas International is a large, international computer consulting company.

Due to the enormous growth of the company, it has become necessary to create a payroll program, which calculates employee salaries.

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.

The record should consist of the following fields for each employee:
First Name
Last Name
Social Security Number
Gender (Male or Female)
Hours Worked
Rate

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.
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 file or database, when the program is rerun.

Please comment your program adequately and name it PayRoll.c(Points will be deducted if there are no comments, or the program is incorrectly named).

Note : You must use Link list to solve this problem. For less credit have an
Array of 20 students.

Your employers at Abbas International wish you lots of success on your Final Assignment.

Suppose you want to develop a program to play lottery. The program randomly generates a Lottery of a three-digit number( any number from 100 to 999), prompts the user to enter a three-digit number, and determines whether the user wins according to the following rule:
1. If the user matches the lottery in exact order , the awards is $100,000.
2. If the user input matches the lottery digits, the awards is $50,000.
3. If two digit in the user input matches a digit in the lottery, the awards is $30,000.
4. If one digit in the user input matches a digit in the lottery,
the awards is $10,000.
Sample:
The winning number is 865.

Your ticket is 865 then 100000
Your tickect is 686, or 568,.. all digits are right but not in order
You get 50000
Your ticket is 860, or 186 .. then 30000
Your ticket is 800, 706, 600.. just one digit much you get
10000
Else
0

Problem Description:
Credit card numbers follow certain patterns. A credit card number must have between 13 and 16 digits. It must start with:
4 for Visa cards
5 for Master cards
37 for American Express cards
6 for Discover cards

In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine if a card number is entered correctly or if a credit card is scanned correctly by a scanner. Almost all credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustration, consider the card number 4388576018402626):

1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number.
2 * 2 = 4
2 * 2 = 4
4 * 2 = 8
1 * 2 = 2
6 * 2 = 12 (1 + 2 = 3)
5 * 2 = 10 (1 + 0 = 1)
8 * 2 = 16 (1 + 6 = 7)
4 * 2 = 8

2. Now add all single-digit numbers from Step 1.
4 + 4 + 8 + 2 + 3 + 1 + 7 + 8 = 37

3. Add all digits in the odd places from right to left in the card number.
6 + 6 + 0 + 8 + 0 + 7 + 8 + 3 = 38

4. Sum the results from Step 2 and Step 3.
37 + 38 = 75

5. If the result from Step 4 is divisible by 10, the card number is valid; otherwise, it is invalid. For example, the number 4388576018402626 is invalid, but the number 4388576018410707 is valid.

Write a program that prompts the user to enter a credit card number as a long integer. Display whether the number is valid or invalid.
