Copy the Payroll program

• Make a copy of the Payroll program from the folder
  \\Dragon\cls_mcdowell\CS 420\payroll\.
  The program is contained in the files:
  • employee.h and employee.cpp
  • main.cpp

Add new functions.

• In employee.cpp we see identical code in three different places to print the basic employee information. This redundancy is a clear signal that we could probably do a better job of organizing our code. Add a function PrintCheckInfo to the Employee class that prints the basic information that is common to all checks. Then modify the versions of PrintCheck in the derived classes to call PrintCheckInfo.

• Declare and define a virtual function CalculatePay that performs the necessary calculation of the value for netPay for the derived classes. Then modify the versions of PrintCheck in the derived classes to call CalculatePay.

Add new derived classes.

• Extend the Employee class hierarchy so that class Temporary serves as a base class for two derived classes, Contract and Consultant. Contract employees are Temporary employees who work for an hourly rate (like the Temporary employees in our original hierarchy). Consultants are Temporary employees who work for a fixed, flat rate.

• Rewrite the main program to print checks for these new types of Employees.

Print out and hand in copies of all three files:

• employee.h
• employee.cpp
• main.cpp

If you have extra time, you can continue your work on the final programming project.
