你得dyz是个int啊

@michaelwanghaoyu

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
