   #include<stdio.h>
   
   int main()
   {
     int i, j;
     int arr[4][4] = { {1, 2, 3, 4},
                       {5, 6, 7, 8},
                       {9, 10, 11, 12},
                       {13, 14, 15, 16} };
     for(i = 0; i < 4; i++)
       for(j = 0; j < 4; j++)
         printf("%d ", j[i[arr]] );
   
     printf("\n\n");
   
     for(i = 0; i < 4; i++)
       for(j = 0; j < 4; j++)
         printf("%d ", i[j[arr]] );
   
     return 0;
   }

   j[i[arr]]

   it is another way of writing = *(*(arr + i ) + j );
   similarly for next one....just change indices in the above one.

   Output:
   1234.......up to 16
   Because,
   a[i][j] equivalent to j[i[a]];
