小菜~~~~~~求助！！
各位高手能不能帮我看一下这个程序错在哪了？#include <stdio.h>
#include <malloc.h>
#define NULL 0
#define LEN sizeof(struct list)
struct list
{
int num;
struct list *next;
};
int m,n;
struct list *creat1(void)
{
struct list *head,*p1,*p2;
n=0;
p1=p2=(struct list *)malloc(LEN);
printf("please input the data1:");
scanf("%ld",&p1->num);
head=NULL;
while(p1->num!=0)
{
n++;
if(n==1) head=p1;
else p2->next=p1;
p2=p1;
p1=(struct list *) malloc(LEN);
scanf("%ld",&p1->num);
}
p2->next=NULL;
return(head);
}
