Thread: Linked lists

If you're just trying to back up head to the start of the list after you create the list with the code in your previous post (without my suggested change):

Code:

/* ... */
    while(head->prev != NULL)
        head = head->prev;

That's it!! Thanks alot! But please explain to me why:

Code:

while(head != NULL)

didn't worked?
