computer science project work

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, employee id 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.

21

We would like to thank our computer sir Mr. A.K Shukla, who provided us this opportunity to make a project on “Employee Database Management System” which really helped us to understand the concepts of C++ computer programming.
