    Doubly link list contains pointers to predecessor as well as successor. In Doubly link list each node has two pointers. One pointer points to the next node and the other points to the previous node.
    struct node
        Int data;
        struct node ∗prev;
        struct node ∗next;
    In the above example, pointer named prev will contain the address of previous node and next pointer will contain the address of next node. By using these two pointers we can move in both directions at any time.
