Question

Consider the following code: template Int doublyLinkedList::length()const { ____ } The statement that provides the length of the linked list is ____. A) cout <<< count; B) destroy(); C) return count; D) return next;

Choice D is incorrect because next is a pointer to the next node and it does not represent the length of the linked list.
