Computer science project work Computer science project work Document Transcript

  • This program is very useful in real life situation forproviding instant information of Employees workingunder any company, department. It also stores theinformation about employees monthly salary, employeeid and designation.In this c++ program we can modify , add, delete, recalland list the records.Being OOP concept available, we can add or removefunction anytime we need and even add classes andderived classes for further improvement of the programWithout recording. 2

  • To make this project we have taken source from a book“Computer Science With C++” written by Sumita Aroraand “let us c++” written by Yashwanth Kanethkar.And taken help of our computer teacher Mr. A.K Shuklasir. 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 reallyhelped us to understand the concepts of C++ computerprogramming. 22
