and this is an example

#include<iostream>
#include<ctime>
#include<cstring>
#include<iomanip>

using namespace std;


int add(int[][6],char [][10],char[][10],char [][10],int);// to add new employ.

void display(int [][6],char [][10],char [][10],char [][10],int );// to display all employes

int Age(char[][10],int );// to calculate Age of employ.

void cmp_ID(int [][6],char [][10],char [][10],char [][10],int );// to compear ID

void cmp_N(int [][6],char [][10],char [][10],char [][10],int );// compar by name.

void swap(int [][6],char [][10],char [][10],char [][10],int );// swap between to employ.

void search(int [][6],char [][10],char [][10],int);// search.

int search_ID(int,int[][6],int );// search py ID of employ.

int search_L_N(char [],char [][10],int );//search by last name.

int search_F_N(char [],char [][10],int );// search by first name
