你得`dyz`是个int啊

```
long long n,p,r;
cin>>n;
cin>>p>>r;
double v=r*1.0/p,tmp;
for (int i=0;i<n-1;i++){
cin>>p>>r;
tmp=r*1.0/p;
if (v-tmp>0.05) cout<<"worse"<<endl;
else if (tmp-v>0.05) cout<<"better"<<endl;
else cout<<"same"<<endl;
}
```
这么写，你的代码中
```
if (1.0*y/x-dyz>=0.05)//把等号去掉
{
cout<<"better"<<endl;
}
else if (dyz-1.0*y/x>=0.05) //把等号去掉
{
cout<<"worse"<<endl;
}
```
你代码里等号太多了
