delete last node

Hey guys im trying to delete the last node in a doubly linked list so far i have traversed and found the end using a while loop then making PREVIOUS which is now the last one to equal NULL. Then i am freeing the node that i have malloced would this work for a doubly linked list?

Code:

---

while(current->next !=NULL)
{
  previous = current;
  current = current->next;
}
previous->next = NULL
free(current)

---

Yes. Did you even think about the problem before asking here ? I mean this is probably your 5th thread about the same easy data structure and for every problem there is, you create a new topic and ask the same mindless questions instead of using your brain and coming up with the solution yourself.

Yes. You don't have to worry about any pointers other than previous->next because you're deleting the last node and don't have to update any back pointers.

I was only asking if this was correct i may not be a genious but i am trying and i only ask for advice on how to approach it

Thanks Noir thats what i thought
