      In contrast, a linked list allocates space for each element separately in its own block of memory called a "linked list element" or "node". The list gets is overall structure by using pointers to connect all its nodes together like the links in a chain. Each node contains two fields: a "data" field to store whatever element type the list holds

Traversal is allowed only one way and there is no going back. A doubly linked list is a list that has two references, one to the next node and another to previous node. Doubly linked list ...

Linked lists are very useful in situations where the program needs to manage memory very carefully and a contiguous block of memory is not needed. An array of linked lists is an important data structure that can be used in many applications.

      Doubly Linked Lists A doubly linked list is a list that contains links to next and previous nodes. Unlike singly linked lists where traversal is only one way, doubly linked lists allow traversals in both ways. A generic doubly linked list node can be designed as: typedef struct node { void* data; struct node* next; struct node* prev; } node;

      Linked List Ground Rules All of the linked list code in this document uses the "classic" singly linked list structure: A single head pointer points to the first node in the list. Each node contains a single.next pointer to the next node. The .next pointer of the last node is NULL. The empty list is represented by a NULL head pointer.
