Program for Employee Management System

Last Updated : 02 Mar, 2023

A Employee’s Management System (EMS) is a software built to handle the primary housekeeping functions of a company. EMS help companies keep track of all the employees and their records. It is used to manage the company using computerized system.

Aim of Employee’s Management System:

Built The Employee Table.
Insert New Entries.
Delete The Entries.
Search A Record.

Data of the Employee’s:

Name
Employee ID
Designation
Experience
Age

Approach:

For storing the data of the employee, create a user define datatype which will store the information regarding Employee. Below is the declaration of the data type:

struct employee {
  string name;
  long int code;
  string designation;
  int exp;
  int age;
};

Building the Employee’s table: For building the employee table the idea is to use the array of the above struct datatype which will use to store the information regarding employee. For storing information at index i the data is stored as:

struct employee emp[10];
emp[i].name = "GeeksforGeeks"
emp[i].code = "12345"
emp[i].designation = "Organisation"
emp[i].exp = 10
emp[i].age = 10

Deleting in the record: Since we are using array to store the data, therefore to delete the data at any index shift all the data at that index by 1 and delete the last data of the array by decreasing the size of array by 1.
Searching in the record: For searching in the record based on any parameter, the idea is to traverse the data and if at any index the value parameters matches with the record stored, print all the information of that employee.

Below is the implementation of Employee Management system in C:

C++

// C++ program for the above approach
#include <bits/stdc++.h>
 
#define max 20

};

// data in the form of the Structure
// of the Array
