c语言链表运行的时候出现乱码

Question

学链表的时候不知道为什么会有一行乱码
（学编程真快乐，就是搞不懂）
代码如下：
#include<stdio.h>
#include<stdlib.h>
char* gets(char* str);
typedef struct NODE {
char name[9];
int num;
struct NODE* next;
}node;

node* putin() {
int num = 1;
node* head ;
node* newnode;
head = (node*)malloc(sizeof(node));
node* nownode = head;

while (1)
{
    int a = 1;
    printf("数字：\n");
    scanf_s("%d", &num);
    if (num != 0) {
        newnode = (node*)malloc(sizeof(node));
        newnode->next = NULL;
        printf("字符：\n");
        gets(nownode->name,getchar());
        newnode->num = num;
        nownode->next = newnode;
        nownode = newnode;
    }
    else {
        goto a;
    }
}a:
printf("-----分割线-----\n");
printf("-----分割线-----\n");
return head;

}

void put(node* head)
{
node* temp = head->next;
while (temp != NULL) {
printf("数字：");
printf("%d\n", temp->num);
printf("字符：");
printf("%s\n", temp->name);
}
}

int main() {
node* head=NULL;
head = putin();
put(head);
return 0;
}

运行的时候就出现了乱码：

就是第一次输入的字符会在最后变成乱码输出

修改过的加了备注，仅供参考！谢谢！

#include<stdio.h>
#include<stdlib.h>
char *gets(char *str);
typedef struct NODE
{
    char name[9];
    int num;
    struct NODE *next;
} node;

node *putin()
{
    int num = 1;
    node *head;
    node *newnode;
    head = (node *) malloc(sizeof(node));
    node *nownode = head;

    while (1)
    {
        int a = 1;
        printf("数字：\n");
        scanf("%d", &num);//自行改回scanf_s
        getchar();
        if (num != 0)
        {
            newnode = (node *) malloc(sizeof(node));
            newnode->next = NULL;
            printf("字符：\n");
            scanf("%s",newnode->name);//被修改过//自行改回gets
            newnode->num = num;
            nownode->next = newnode;
            nownode = newnode;
        }
        else
        {
            goto a;
        }
    }
  a:
    printf("-----分割线-----\n");
    printf("-----分割线-----\n");
    return head;
}

void put(node * head)
{
    node *temp = head->next;
    while (temp != NULL)
    {
        printf("数字：");
        printf("%d\n", temp->num);
        printf("字符：");
        printf("%s\n", temp->name);
        temp=temp->next;//这里被添加了一句
    }
}

int main()
{
    node *head = NULL;
    head = putin();
    put(head);
    return 0;
}
