很水的题，判断读入8个二进制转换后用ASCII码输出就解决了。
代码如下：
#include<stdio.h>#include<ctype.h>int main(){ int i = 0, num; int n[10] = {0}, tmp; for (; (tmp = getchar()) != EOF;) { if (tmp == ' ') { n[i] = 0; i ++; } if (tmp == 'o') { n[i] = 1; i ++; } //printf("i = %d, n[%d] = %d\n", i, i - 1, n[i - 1]); if (i == 8) { i = 0; num = n[0]*128+n[1]*64+n[2]*32+n[3]*16+n[4]*8+n[5]*4+n[6]*2+n[7]*1; printf("%c", num); } } return 0;}
