>>9182008consider this
int d1[5] = {1, 2, 3, 4, 5};
now consider this
int d2[5][5] = {{1, 2, 3, 4, 5}, {1, 2, 3, 4, 5}};
now check the image, probably not the best image but in the case of a 4D dimensional array or just the 4th dimension. You have just a copy of the first set of dimensions if that makes sense.
