那里better也不行。。。打错了

@Czh116489 小数

 x=a/sample1;

 x=a*1.0/sample1;

试一下，数据类型换double吧

@Czh116489 还有这句

y=good/sample;

y=good*1.0/sample;

@Czh116489 帮你改了一下，AC了

#include<stdio.h>
int main()
{
    double n,x,y;
    double sample1=0,a=0,good=0,sample;
    scanf("%lf",&n);
    for(int i=1;i<=n;i++)
    {

        if(i==1)
        {
            scanf("%lf %lf",&sample1,&a);
            x=a*1.0/sample1;

        }
        else
        {
            scanf("%lf %lf",&sample,&good);
            y=good*1.0/sample;
            if(y-x>0.05)
            puts("better");
            else if(x-y>0.05)
            puts("worse");
            else
            puts("same");
        }
    }

    return 0;
}
