Iteration over Linked Lists (cont)

Check if list contains an element: 

int inLL(NodeT *list, int d) {
   NodeT *p;
   for (p = list; p != NULL; p = p->next)
      if (p->data == d)      // element found
         return true;
   return false;             // element not in list
}

Print all elements: 

void showLL(NodeT *list) {
   NodeT *p;
   for (p = list; p != NULL; p = p->next)
      printf("%6d", p->data);
}
