typedef
struct

name[20];
//用户名
char
password[8];
//用户密码
int
power;
//权限判断

}
user;
user
yh[100]={100000,"gavin","gavine",1,100001,"wnag","wangf",2};
int
length
=
2;
int
checkuser(long
num,
const
char
*nm,
const
char
*pwd)
{
int
i;
for
(i
=
0;
i
<
length;
++i)
{
if
(yh[i].number
==
num
&&
!strcmp(yh[i].name,
nm)
&&
!strcmp(yh[i].password,

{
if
(1==yh[i].power)
return
1;
else
return
2;
}
}
}
void
main()
{
printf("%d\n",
checkuser(100000,
"gavin",
"gavine"));
}
