解题报告

第一眼不懂，第二眼略懂，第三眼水题。。。

有个地方需要注意，就是输入和输出的地方，可以定义数组输入，每次输入类似| o   .  o|
返回一个字符，其实'|'，'.'，'_'都不用考虑，只要考虑'o'的情况。

每次输入的数组好像都是11个字符大小的，除第一行和最后一行外第一个和最后一个恒为'|'，第七字符恒为'.'，这样就可以定义一个大小为12的字符数组。

#include<stdio.h>  int main()  {      char str[12];      int i,n;      while(gets(str)!=NULL)      {          if(str[0]=='_')          continue;          n = 0;          for (i=2;i<=9;i++)          {              if(str[i]=='o')                  switch(i)                  {                      case 2:n=n+64;break;                      case 3:n=n+32;break;                      case 4:n=n+16;break;                      case 5:n=n+8;break;                      case 7:n=n+4;break;                      case 8:n=n+2;break;                      case 9:n=n+1;break;                  }          }          putchar(n);      }      return 0;  }
