从样例输入输出可以很容易看出，输入纸带的每一行是一个ASCII表示的字符，'o'表示1，' '表示0，中间的'.'是个干扰字符，删去即可

写程序每次读一行，算出ASCII码值输出字符即可

 

 1 #include<iostream>
 2 #include<cstdio>
 3 
 4 using namespace std;
 5 
 6 char s[20];
 7 
 8 int main()
 9 {
10     gets(s);
11 
12     while(gets(s))
13     {
14         if(s[0]=='_')
15             break;
16 
17         for(int i=6;i<=8;i++)
18             s[i]=s[i+1];
19 
20         int res=0;
21 
22         for(int i=1;i<=8;i++)
23         {
24             if(s[i]=='o')
25                 res+=(1<<(8-i));
26         }
27 
28         putchar(res);
29     }
30 
31     return 0;
32 }
