这二个是字符数组，p1->name这个是数组名，代表的是起始地址，输入的时候，不能加&,这二个都是这样的。对你的程序我给你小小的调整了一下，都是在这二处，然后就好用了，程序如下：
#include<stdio.h>
#include<malloc.h>
#include<string.h>
#define NULL 0
#define LEN sizeof(struct student)
struct student
{ char name[20];
char addr[50];
long tel;
long post_number;
struct student *next;
};
int n;
struct student *creat(void)
{ struct student *head;
struct student *p1,*p2;
n=0;
p1=p2=(struct student *)malloc(LEN);
puts("input name:");
scanf("%s",p1->name);
puts("input addr:");
scanf("%s",p1->addr);
puts("input tel");
scanf("%ld",&p1->tel);
puts("input post_number:");
scanf("%ld",&p1->post_number);
//scanf("%s,%s,%ld,%ld",&p1->name,&p1->addr,&p1->tel,&p1->post_number)
