My understanding is this: delete() frees the memory space allocated already. However, if you do not reset the pointer to NULL, it will continue to point to a freed memory block (which may subsequently be allocated for some other uses) and lead to segmentation fault or mysterious behaviour with unexpected value if you happen to access that pointer. To safeguard, reset the pointer to NULL as soon as the memory location is freed.
