I have written a logic to find out the intersection of two arrays. Please review my logic and guide me if my logical approach is not correct.

#include<stdio.h>  void intersect(int a1[][2], int a2[][2],int row, int col)  {   int i = 0, j= 0, x = 0, y = 0;  for(i = 0; i <row ; i++) {     for(j = 0 ; j < col ; j++)     {             for(x = 0; x < row ; x++)             {                 for(y = 0; y < col ; y++)                 {                     if(a1[i][j] == a2[x][y])                          printf("%d\t",a1[i][j]);                  }             }     } } }  int main() {      int arr1[2][2]={{2,5},{6,8}};      int arr2[2][2]={{1,2},{8,8}};      row = (sizeof(arr1)/sizeof(arr1[0]));      col = (sizeof(arr1[0])/sizeof(arr1[0][1]));      intersect(arr1,arr2,row,col); }
