This program is very useful in real life situation for

providing instant information of Employees working

under any company, department. It also stores the

information about employees monthly salary, employeeid and designation.

In this c++ program we can modify , add, delete, recall

and list the records.

Being OOP concept available, we can add or remove

function anytime we need and even add classes and

derived classes for further improvement of the program

Without recording.

To make this project we have taken source from a book

Computer Science With C++written by Sumita Arora

and let us c++ written by Yashwanth Kanethkar.

And taken help of our computer teacher Mr. A.K Shukla

sir.
