Question

Take the code we've provided for the Employee class (Employee.h

and the Manager class (Manager.h

Add methods to the classes named:

setName()

setPayRate()

setSalaried()

that let users change the corresponding fields. Take advantage of the inheritance relationship between Employee and Manager--you only need to add each of those methods to 1 class.

Write a Supervisor class. A supervisor is responsible for employees in a specific department and must:

Have a field to store the department name (as a string).

Have getDept() and setDept() methods to access the department field.

Always be salaried (i.e., pay for a single pay period is fixed, no matter how many hours are worked).

Have a constructor that takes initial values for all fields.

What class should Supervisor inherit from?

Your code should compile and run correctly with the test program: Empltest.cpp

.

Upload- your source files: Employee.h, Manager.h, and new file Supervisor.h)
