Semester: Spring 2015

CS304: Object Oriented Programming

Total Marks: 20


Due Date: 08/06/2015




Please read the following instructions carefully before submitting assignment. It should be clear that your assignment will not get any credit if:


  • The assignment is submitted after due date.
  • The submitted assignment does not open or file is corrupt.
  • Assignment is copied(partial or full) from any source (websites, forums, students, etc)


Note: You have to upload only .cpp file. Assignment in any other format (extension) will not be accepted and will be awarded with zero marks. For example, if you submit code in .doc (Microsoft Word Document) or .txt files or .exe file, no reward will be given in any case.





The objective of this assignment is to provide hands on experience of:


  • Classes and objects
  • Constructors and destructors
  • Setter and Getter functions
  • Static data member
  • Member initializer list
  • Copy constructor and deep copy





  • Code should be properly indented and well commented.
  • Follow C/C++ guide lines while writing variable names, function names etc
  • Use only dev-C++ for this assignment.

Problem Statement:  


In this assignment you will be creating a class named Employee.


Employee class has the following data members:

  • Employee ID.
  • Employee Name
  • Department
  • Employee Salary
  • Static data member which will hold the value of total no. of employees



Employee class must have the following member functions:





Default constructor for Employee class, which will set employee id  to 0, employee name to NULL, employee department to NULL and salary to 0.0

Employee(int, char *, char *, float);

It will take employee id, employee name, department and salary as arguments and initialize their values using member initializer list

Employee(Employee &); 

Copy constructor which will initialize one object with another object using deep copy

Setter functions

You have to define setter function for each data member which will take a value as an argument and set their values

Getter functions

You have to define getter function for each data member which will return the values of their data members


This function will calculate the net pay of an employee based on his salary


This function will display the values of all data members of class


Destructor of Employee class which will decrement the value of static data member of class



calcNetPay():  This function will calculate net pay of an employee based on his salary as:

If salary is less than and equal to 10,000 then tax is 0.

If salary is greater than 10,000 and less than equal to 20,000 then tax is 5%.

If salary is greater than 20,000 and less than equal to 30,000 then tax is 7%.

The tax on the salary greater than 30,000 is 10%.

Note: On creation of each object, the value of static data member should be incremented.






Within main() function, create an array of 5 objects of class Employee. Second object should be initialized with the first object.


Now, use for loop to call calcNetPay() and display() functions for each object.


You can create objects as follow:

Employee emp1(5, "Ahmad", "Accounts", 20000 );

Employee emp2(emp1) ;

Employee emp3(10, "Ayesha", "Accounts", 25000);

Employee emp4(3, "Hassan", "Administration", 10000);

Employee emp5(6,  "Arsalan", "Administration", 35000);


Sample output of the program:
