Payroll System Using Inheritance and Polymorphism $($C$++)$

You need to implement the following header file and classes.

$1.$ Define the following constants in a header file called Employee.h

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

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

$2.$ 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.

$3.$ 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 $160)$

putData that displays the following information:

ID Employee number :$\_\_\_\_\_\_\_\_\_$

Employee name: $\_\_\_\_\_\_\_\_\_\_$

Full Time

Monthly Salary: $\_\_\_\_\_\_\_\_\_$

$4.$ 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

FU $-1\mathrm{.}4$ times faculty's monthly salary

putData that displays the following information:

ID Employee number :$\_\_\_\_\_\_\_\_\_$

Employee name: $\_\_\_\_\_\_\_\_\_\_$

XXXXX Professor where XXXXX can be Assistant, Associate or Full

Monthly Salary: $\_\_\_\_\_\_\_\_\_$

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

Attributes

Hours worked per week

Default argument and argument constructors

Public Methods

set and get

The method monthlyEarning returns monthly salary which hourly rate multiplied by hours worked per week multiplied by four.

putData that displays the following information:

ID Employee number :$\_\_\_\_\_\_\_\_\_$

Employee name: $\_\_\_\_\_\_\_\_\_\_$

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.

Total monthly salary for all the staff

Total monthly salary for faculty

Total monthly salary for part$-$time

Total monthly salary for all employees
