我才初中
很想帮你,,
可惜没办法~~~
p7=NULL;
printf("您所找的信息是：\n");
printf("%d %d",p7->num,p7->shouzhi);
这句有问题
p7空了
就不能指向 p7-num了
看了一下你的程序
好像错在void search(struct user *head,int snum)
的输出部分p7=NULL; 的位置好像错了
别的地方倒没有什么问题
帮你改了一下 不知道是不是你要求的
#include "stdio.h"
#include "malloc.h"
#include "conio.h"
#define LEN sizeof(struct user)
struct user *head;
int snum;
void print(struct user *head);
void search(struct user *head,int snum);
struct user
{
int num;
int shouzhi;
char menlei[10];
char shijian[15];
struct user *next;
};
struct user *creat();
void main()
{
int m;
struct user *stu;
head=creat();
print(head);
printf("请输入您想差找的
