我在把下面函数放到一个程序里运行时出现“Too many types in declaration”,
而仅仅main（）调用下面函数却能运行成功，也就是说，函数本身应该没什么问题。可是为什么会出现那情况呢？
我的QQ：93316608
int password_comp(char *s)
{
char ch,cch;
char s1[80];
int i=-1;
int j,len;
memset(s1,'\0',80);
cch='x'; len=strlen(s);
printf("\nplease enter the password:");
do { ch=getch();
if(ch!='\r')
{ printf("%c\a",cch);
i++;s1[i]=ch;}
}while(ch!='\r');
printf("\n\a\a\a\a\a\a\n");
j=strlen(s1);
if((j!=len)||(memicmp(s1,s,j)))
return(0);
else
return(1);
}
void pass(void)
{
int i,kout;
clrscr();
printf("This is library system.\n ");
for(i=0;i<3;i++)
{kout=password_comp("abcdefgh");
if(i==2) { exit(0); }
if(kout==0) printf("Password error!!!Press any key to continue...");
if (kout==1){ printf("\n Password is right!!! You are welcome!\nPress any key to continue... ");
getch();
clrscr();
break;
}
}

不好意思，拷上来时少个}

I AM WAITING！！

[babybabygo]

郁闷

[babybabygo]

要是懂的话就用不着花很多时间吧

[yzb1000]

struct library
{ char category;
char bookname[20];
char author[10];
char information[50];
struct library*next;
};
//少个分号

[zhouhu]

晕

[金笛子]

不是错误
是变量太多了
每个函数包括的数不要总是重复吗！
虽然不好用全局的 借用一下还是可以的吗！
试试看

[babybabygo]

是因为少了个；
不好意思

[YuKye]

!!!!

[feigehao]

你那个MEM。H 是什么头文件呀

[robertnet]

：） 太长了，分又少！

[Zark]

请把这句话
"我在把下面函数放到一个程序里运行时出现“Too many types in declaration”,

再解释一下.
