请用C语言创建一个不带头结点的单链表

好的，以下是创建一个不带头结点的单链表的示例代码：

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

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

int main() {
    struct Node *head = NULL, *tail = NULL, *temp = NULL;
    int num;

    printf("请输入整数，输入 -1 结束：\n");
    scanf("%d", &num);

    while (num != -1) {
        temp = (struct Node *) malloc(sizeof(struct Node));
        temp -> data = num;
        temp -> next = NULL;
    
        if (head == NULL) {
            head = temp;
            tail = temp;
        } else {
            tail -> next = temp;
            tail = temp;
        }

        scanf("%d", &num);
    }

    printf("链表的值为：\n");
    temp = head;

    while (temp != NULL) {
        printf("%d ", temp -> data);
        temp = temp -> next;
    }

    return 0;
}

希望这能够帮到您！
