给我一段c语言的链表代码

以下是一段简单的C语言链表代码：

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

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

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

int main() {
    struct Node* head = NULL;
    struct Node* second = NULL;
    struct Node* third = NULL;

    head = (struct Node*)malloc(sizeof(struct Node));
    second = (struct Node*)malloc(sizeof(struct Node));
    third = (struct Node*)malloc(sizeof(struct Node));

    head->data = 1;
    head->next = second;

    second->data = 2;
    second->next = third;

    third->data = 3;
    third->next = NULL;

    printList(head);

    return 0;
}

这段代码创建了一个简单的链表，包含三个节点，每个节点都包含一个整数和指向下一个节点的指针。主函数中创建了三个节点，然后将它们连接起来，最后通过调用printList函数打印出链表中的所有元素。
