我也是WA了几次,不过测试数据没有什么特别的啊:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
main()
{
int s[]={128,64,32,16,8,4,2,1};
int n,i,j,res;
char t[100];
scanf("%d",&n);
getchar();
while(n-->0)
{
gets(t);
for(i=0;i<4;i++)
{
res=0;
for(j=0;j<8;j++)
res+=s[j]*(t[j+8*i]-'0');
if(i!=0) printf(".");
printf("%d",res);
}
printf("\n");
}
system("pause");
}
