Modify and rewrite to do the following tasks:

1. Save all employees entered on the keyboard into a file called “Employees.dat”.

2. After the calculation of each employee payment is done, instead of printing all of the employee payments on screen save him or her information into a file called “Payments.dat”.

3. Enter five to ten samples of employees.

4. There should be a .cpp file, a Employees.dat file, and Payments.dat file
