关于帐号密码的问题
突发奇想，写了一段码
程序代码：#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<conio.h>
#define LEN sizeof(struct zhanghu)
struct zhanghu
{
char zhanghu_zhanghao[20];
char zhanghu_mima[16];
struct zhanghu *next;
};
int n;
int zhuce(struct zhanghu *head,struct zhanghu *p1,struct zhanghu *p2)
{
int len,ch;
while(p1->zhanghu_zhanghao!=0)
{
n=n+1;
if(n==1)head=p1;
else p2->next=p1;
p2=p1;
p1=(struct zhanghu *)malloc(LEN);
printf("帐号：");
lable1:
gets(p1->zhanghu_zhanghao);
len=strlen(p1->zhanghu_zhanghao);
if(len>20)
{
printf("过长\n");
printf("请重新输入帐号：");
goto lable1;
}
if(len<6)
{
printf("过短\n");
printf("请重新输入帐号：");
goto lable1;
}
printf("\n密码：");
lable2:
while((p1->zhanghu_mima=getch())!='\n')
printf("*");
len=strlen(p1->zhanghu_mima);
if(len>16)
{
printf("过长\n");
printf("请重新输入密码：");
goto lable1;
}
if(len<6)
{
printf("过短\n");
printf("请重新输入密码：");
goto lable1;
}
}
}
/*void denglu(struct zhanghu head,struct zhanghu *p1,struct zhanghu *p2)
{
char zhanghaoa[],mimaa[];
printf("帐号：");
gets(zhanghaoa);
printf("\n密码:");
gets(mimaa);
}*/
struct zhanghu *creat(void)
{
struct zhanghu *p1,*p2;
struct zhanghu *head;
char a;
head=NULL;
n=0;
p1=p2=(struct zhanghu *)malloc(LEN);
zhuce(head,p1,p2);
/*printf("是否注册帐号Y，或N，或登录L:");
scanf("%c",&a);
if(a='Y'||'y')
zhuce(head,p1,p2);
if(a='N'||'n')
denglu(head,p1,p2);*/
}
/*还没写完,为什么会报错？我觉得已经对了吧！
*/
