Employee Management System Using C++

Introduction to Employee Management System Using C++

Employ management system using C++ is a menu-driven program that allows us to add, update, delete and search records of an employee working in an organization. The program employee management system stores employee ID, name, post, department, and salary of the employee. Initially, it has no data. Thus, we have to add employee records choosing appropriate options in this program (i.e. selecting option #1). Previously we had posted Employee Management System Using C with the same features.

Employee Management system using C++ program uses EmpID as a unique identifier (i.e. primary key) to recognize employee. So, we can’t add two employees having the same ID. After successful entry of records of some employees, we can search records on the basis of ID or department. We can search particular employees from ID choosing option #2 and if we want to see all employees working in a department, we have to choose another option (i.e. option#3 in the menu). We can list all employee records also using option #4 in the menu. Again, we can update and delete existing records. Thus, this project is useful to manage employee records in an organization.

Before going to the software code part, let’s see the output. The project Employee Management System Using C++ is compiled using TurboC++

The above given source code is only working in turbo c++ why not working in Dev-c.

  Here are few parameter and keyword which is not supported by DEV-C++

Websites like this are really good, because they help other people who need help or are weak in programming . Keep up the good work. God bless
