???????????? ?????????????????? ??????????????? ?????? ????????? ?????????????????? (C ???????????? ?????????) - Code example of Doubly Linked List (in C language) in Hindi

Input: C

#include 

// Node structure

struct Node {

    int data;

    struct Node* prev;

    struct Node* next;

};

// Function to create a new node

struct Node* createNode(int data) {

    struct Node* newNode = (struct Node*)malloc(sizeof(struct Node));

    newNode->data = data;

    newNode->prev = NULL;

    newNode->next = NULL;

    return newNode;

}

// Function to print the list forward

void displayForward(struct Node* head) {

    struct Node* temp = head;

    printf("Forward: ");

    while (temp != NULL) {

        printf("%d ", temp->data);

        temp = temp->next;

    }

    printf("\n");

}

// Function to print the list backward

void displayBackward(struct Node* tail) {

    struct Node* temp = tail;

    printf("Backward: ");

    while (temp != NULL) {

        printf("%d ", temp->data);

        temp = temp->prev;

    }

    printf("\n");

}

int main() {

    // Create three nodes

    struct Node* head = createNode(10);

    struct Node* second = createNode(20);

    struct Node* third = createNode(30);

    // Connect the nodes

    head->next = second;

    second->prev = head;

    second->next = third;

    third->prev = second;

    // Display the list in both directions

    displayForward(head);

    displayBackward(third);

    return 0;

}

Output of the Program:

?????? ?????? ????????? ???????????? Doubly Linked List ??????????????????????????? ?????? ??????????????????, ?????? ?????????????????? ????????? ?????? ????????? ????????????:

Plain

Forward: 10 20 30

Backward: 30 20 10

Doubly Linked List vs Singly Linked List in Hindi
