Problem Statement:
Company maintains employee information as employee ID, name, designation and salary. Allow user to add, delete information of employee. Display information of particular employee. If employee does not exist an appropriate message is displayed. If it is, then the system displays the employee details. Use index sequential file to maintain the data.
Code:
#include <bits/stdc++.h>
#define max 20
using namespace std;
// Structure of Employee
struct employee {
string name;
long int code;
string designation;
int exp;
int age;
};

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

sortemp[max], sortemp1[max];
