Part I $-$ Polymorphism

Payroll System Using Inheritance and Polymorphism

You need to implement the following header file and classes.

Define the following constants in a header file called Employee.h

FACULTY$\_$MONTHLY$\_$SALARY $=5000\mathrm{.}00$

STAFF$\_$MONTHLY$\_$HOURS$\_$WORKED $=160$

Implement an abstract class Employee with the following requirements:

Attributes

last name $($String$)$

first name $($String$)$

ID number $($String$)$

Default argument constructor and argument constructors.

Public Methods

putData that displays the following information:

ID Employee number :

Employee name:

pure virtual method monthlyEarning that returns the monthly earning.

Implement a class called Staff extending from the class Employee with the following requirements:

Attribute

Hourly rate

Default argument and argument constructors

Public Methods

@ get and set

The method monthlyEarning returns monthly salary $($hourly rate times $160)$

Implement a class Education with the following requirements:

Attributes

Degree $($MS or Ph$.$D$.)$ String type

Major $($Engineering$,$ Chemistry, English, etc $...)$ String type

Research $($number of researches$)$

Default argument and argument constructors.

Public methods

@ get and set

Implement a class Faculty extending from the class Employee with the following

requirements:

Attributes

Level $($use enum statement$)$

$"$AS$"$: assistant professor

$"$AO$"$: associate professor

$"$FU$"$: professor

Education object

Default argument and argument constructor

Public Methods

@ get and set

The method monthlyEarning returns monthly salary based on the

faculty's level.

AS $-$ faculty monthly salary

AO $-1\mathrm{.}2$ times faculty's monthly salary

Hours works per month:

Monthly Salary:

Implement a test driver program that creates an array or a vector of class Employees to store the objects Staff, Faculty,

and Partime.

Using polymorphism, display all employees using the method putData.

Use the following data to create Employee objects in your program.

Part II $-$ File processing

Create a main function with the following menu:

$$a$--$ add data for an employee from a user

$$d$--$ display data for all employees

$$w$--$ write all employee data to file

$$r$--$ read all employee data from file
