Multidimensional array in c

The individual elements are-
arr[0][0][0], arr[0][0][1], arr[0][0][3], arr[0][1][0]……….arr[0][3][3] arr[1][0][0], arr[1][0][1], arr[1][0][3], arr[1][1][0]……….arr[1][3][3] The total elements in the above 3-D array are
=2*4*4 =32

int arr[2][4][4]={
{1,5,6,7} /* matrix 0 and row 0 */
{4,3,2,6} /* matrix 0 and row 1 */

{1,2,3,4} /* matrix 1 and row 1 */
{23,44,5,6} /* matrix 1 and row 2 */
