c - C 中的链表；分段故障

Question

我正在用 C 语言为链接列表创建这个程序，以获取用户的输入，以创建一个节点并将头指向该节点并打印节点元素的值和地址。我运行时遇到段错误，请帮我解决问题。

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

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

struct Node* head;

void main() {
    head = NULL;
    struct Node* temp = (struct Node*)malloc(sizeof(struct Node));
    printf("Enter the number you want in node\n");
    scanf("%d",(int *)temp->data);
    temp->next = NULL;
    head = temp;
    printf("the address of node  is %p",head);
    printf("the value is %d",temp->data);
}

//try this code
#include<stdio.h>
#include<stdlib.h>
struct Node {
   int data;
  struct Node* next;
};
struct Node* head;

void main() {
   head = NULL;
  struct Node* temp = (struct Node*)malloc(sizeof(struct Node));
  printf("Enter the number you want in node\n");
  scanf("%d",&temp->data);
  temp->next = NULL;
  head = temp;
  printf("the address of node  is %p",head);
  printf("the value is %d",temp->data);
}
