C++ please write a program that compiles and run. PA1 program is below:

In this project, you will modify PA1 by creating Employee class and apply separate compilation. Your program must not interact with the user to receive inputs for efficiency in testing programs, while meeting the following requirements.

Employee class

Change the struct data type Employee to a class with all preexisting attributes(, or data members, or data fields) and an additional data member named count that keeps track of the number of Employee objects.

Implement the interface that include the following functionalities

An Employee object can be created with its data members set to default values

An Employee object can be created with its data members set to values according to parameters.

An Employee object notifies being out of scope when it is.

Each data member can be retrieved

department and role can be set individually

salary can be increased by 5 - 10 %

department, role and salary can be changed simultaneously.

All data members can be displayed at once

Prevent accidental modification of data members if unnecessary

Prevent multiple inclusion of the Employee class by adding preprocessor directive: ifndef, define, endif

Have the class declaration in .h and define all member functions in .cpp

main() : use and test the Employee class

Create an employee DB with 5 employees by using dynamic array allocation

Before moving to b, make sure that each employee is unique. For this, you can manipulate data members of an employee with your choice.

Display information of all employees on the console

Display the average salary of all employees on the console

Display information of programmers only on the console

Increase the salaries of all managers by random percentage and display the results

Reassign an employee to a different department and role with increased salary and display the result.

Create another employee with a parameter constructor and display the employee information.

Also, display the number of employees.

Release any dynamically allocated memory in your program without memory leak

Reset any pointer variable if it is not used any longer. Otherwise, such pointer becomes a dangling pointer pointing to a memory that has been deleted already.

Apply indentations correctly to make your program readable.

makefile

Provide makefile to apply separate compilation
