One image is worth a thousand words, so here it goes:
arr is something like this in memory:
+---+---+---+---+
| 1 | 2 | 3 | 4 |
+---+---+---+---+
d_ptr would require something like:
+---------+---------+
| pointer | pointer |
+----|----+----|----+
| | +---+---+
| +---> | 3 | 4 |
| +---+---+ +---+---+
+---> | 1 | 2 |
+---+---+
Ie. in arr all the numbers are lied linearly in memory whereas
int **d_ptr is an array of pointers to array of ints.
