数组别在幂里定啊

by 红黑树 @ 2024-05-20 21:10:15

@lzy13915136909 是有效“率”哦，不是个数。

by 红黑树 @ 2024-05-20 21:10:58

@abc1234shi 数组在 main 里有啥问题吗？

by abc1234shi @ 2024-05-20 21:12:01

@红黑树 不然数组里会有随机数

by 红黑树 @ 2024-05-20 21:13:45

@abc1234shi 但是他会用读入冲掉。

@lzy13915136909 1.你应该是输入完一个就输出一个答案。2.是效率差而不是两个数的差

@abc1234shi @红黑树 ，还是没懂...... code

#include<bits/stdc++.h>
using namespace std;
int n,a[1005],b[1005];
int main()
{
    cin>>n;
    for(int i=0;i<n;i++)
        cin>>a[i]>>b[i];
    for(int i=0;i<n;i++)
    {
        if(a[i]-b[i]>0.05)
            cout<<"better"<<endl;
        else
        {
            if(b[i]-a[i]>0.05)
                cout<<"worse"<<endl;
            else
                cout<<"same"<<endl;
        }
    }
    return 0;
}

同样六年级qaq

@lzy13915136909 你第二个循环不要了，加到第一个循环里
