用c语言实现单链表操作

可以使用以下代码实现单链表操作：

#include <stdio.h>
#include <stdlib.h>

typedef struct node {
    int data;
    struct node *next;
} Node;

Node *createNode(int data) {
    Node *newNode = (Node *)malloc(sizeof(Node));
    newNode->data = data;
    newNode->next = NULL;
    return newNode;
}

void insertNode(Node **head, int data) {
    Node *newNode = createNode(data);
    if (*head == NULL) {
        *head = newNode;
    } else {
        Node *current = *head;
        while (current->next != NULL) {
            current = current->next;
        }
        current->next = newNode;
    }
}

void deleteNode(Node **head, int data) {
    if (*head == NULL) {
        return;
    }
    Node *current = *head;
    if (current->data == data) {
        *head = current->next;
        free(current);
        return;
    }
    while (current->next != NULL && current->next->data != data) {
        current = current->next;
    }
    if (current->next == NULL) {
        return;
    }
    Node *temp = current->next;
    current->next = temp->next;
    free(temp);
}

void printList(Node *head) {
    Node *current = head;
    while (current != NULL) {
        printf("%d ", current->data);
        current = current->next;
    }
    printf("\n");
}

int main() {
    Node *head = NULL;
    insertNode(&head, 1);
    insertNode(&head, 2);
    insertNode(&head, 3);
    printList(head);
    deleteNode(&head, 2);
    printList(head);
    return 0;
}

这段代码实现了单链表的创建、插入、删除和打印操作。
