数组别在幂里定啊

@[lzy13915136909](/user/1021693) 是有效“率”哦，不是个数。

@[abc1234shi](/user/941501) 数组在 main 里有啥问题吗？

@[红黑树](/user/413140) 不然数组里会有随机数

@[abc1234shi](/user/941501) 但是他会用读入冲掉。

@[lzy13915136909](/user/1021693) 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

```cpp
#include <iostream>
using namespace std;
int main()
{
int n, a[30][2];
double x, y;
cin >> n;
for (int i = 0; i < n; i++)
cin >> a[i][0] >> a[i][1];
x = 1.0 * a[0][1] / a[0][0];
for (int i = 1; i < n; i++)
{
y = 1.0 * a[i][1] / a[i][0];
if (y - x > 0.05)
cout << "better" << endl;
else if (x - y > 0.05)
cout << "worse" << endl;
else
cout << "same" << endl;
}
return 0;
}

@[abc1234shi](/user/941501) @[红黑树](/user/413140) ，还是没懂......
code
```cpp
#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;
}
```

@[lzy13915136909](/user/1021693) 你第二个循环不要了，加到第一个循环里
