A queue implemented using a linked list follows the FIFO (First In, First Out) principle. The enqueue operation adds elements to the rear, while the dequeue operation removes elements from the front.
Example Code
#include <stdio.h>#include <stdlib.h>// Node structuretypedef struct Node {int data;struct Node* next;} Node;// Queue structuretypedef struct Queue {Node* front;Node* rear;} Queue;// Function to initialize a queueQueue* createQueue() {Queue* q = (Queue*)malloc(sizeof(Queue));q->front = q->rear = NULL;return q;}// Enqueue operationvoid enqueue(Queue* q, int value) {Node* newNode = (Node*)malloc(sizeof(Node));newNode->data = value;newNode->next = NULL;if (q->rear == NULL) {q->front = q->rear = newNode;return;}q->rear->next = newNode;q->rear = newNode;}// Dequeue operationint dequeue(Queue* q) {if (q->front == NULL) {printf("Queue is empty.\n");return -1;}Node* temp = q->front;int data = temp->data;q->front = q->front->next;if (q->front == NULL)q->rear = NULL;free(temp);return data;}// Display the queuevoid display(Queue* q) {if (q->front == NULL) {printf("Queue is empty.\n");return;}Node* temp = q->front;printf("Queue: ");while (temp != NULL) {printf("%d ", temp->data);temp = temp->next;}printf("\n");}// Main function to demonstrate operationsint main() {Queue* q = createQueue();enqueue(q, 10);enqueue(q, 20);enqueue(q, 30);display(q);printf("Dequeued: %d\n", dequeue(q));display(q);return 0;}コピーしました。✕コピー Queue - Linked List Implementation - GeeksforGeeks
