@[洛谷is_the_best](/user/35153) 当然不香，因为有空格

@[breeze末影](/user/242543) 那就getline再循环不行吗
by 绿绵羊 @ 2020-05-24 14:02:45
@[Mine_King](/user/195331) 这个应该没有问题（

反正我不用getchar
by 绿绵羊 @ 2020-05-24 14:03:08
@[洛谷is_the_best](/user/35153) 我就是说getline啊
by Ryo_Yamada @ 2020-05-24 14:03:18

[A了](http://39.98.135.147/showsource.php?id=3654)
```
#include<bits/stdc++.h>
using namespace std;
int main(){
int s=0;
for(int i=0;i<10000;++i)
if(getchar()=='.')
++s;
cout << s;
}
```
