大神们为什么这个代码输出成错误变成这个样子了？

Question

#include
#include
typedef struct splist
{
int data;
splist next;
} splist;
splist *CJ(splist *L)
{
L=(splist)malloc(sizeof(splist));
L->next=NULL;
splist p;
int n,i;
printf("请输入建表的长度");
scanf("%d",&n);
for(i=0;i<n;i++)
{
p=(splist)malloc(sizeof(splist));
printf("请输入数据");
scanf("%d",p->data);
p->next=L->next;
L->next=p;
}
return (splist*)L;
}
int print(splist *L){
splist *s=L->next;
while(s != NULL){
printf("%d ",s->data);
s = s->next;
}
return 0;
}

int main()
{
splist L=(splist)malloc(sizeof(splist));
L=CJ(L);
print(L);
return 0;
}

Answer 1

scanf("%d",p->data);
这里是
scanf("%d",&p->data);
