Answer 1

#include<iostream>

#include<stdlib.h>

using namespace std;

int main () {

   int flag = 0 ;

   int num,arr[5][5] ;

   cout<<"* Enter your array elements:\n" ;

   for(int i=0; i<5;i++){

       for(int j=0; j<5 ;j++){

           cin>>arr[i][j] ;

       }

   }

   

   cout<<"\n* Enter a number to search in the array: ";

   cin>> num ;

   for (int i=0;i<5 ; i++ ){

       for(int j=0 ; j<5 ;j++ ){

           if(num==arr[i][j]) {

               cout<<"\n** Element found and with index ( " <<i<<", " <<j <<" ) ." <<endl;

               flag = 1 ;

               exit(0) ;

           }

       }

   }

     if( flag == 0 ){

               cout<<"\n** Element not found." <<endl;
