@[祁恩葛](/user/331557) 你倒数第4行`cout<<endl; `~~你当初是为什么打上去的~~

@[祁恩葛](/user/331557) 把倒数第4行`cout<<endl;`删掉就过了

```cpp

{

for(int s=1;s<=n;s++)

return 0;

后面我看了下，有$2$处错误：
1. 函数里的$c$未归零
2. $o$不是`double`类型
改过且测过可以$AC$的：
```cpp
#include<iostream>
#include<cmath>
#include<algorithm>
#include<iomanip>
#include<bits/stdc++.h>
using namespace std;
double a(int n) {
int a[1010],c=0;
for(int s=1; s<=n; s++) {
cin>>a[s];
}
sort(a+1,a+n+1);
for(int s=2; s<=n-1; s++) {
c+=a[s];
}
double i=(double)c/(n-2)*1.000;
return i;
}
int main() {
int n,m;
double max=-10.000;
cin>>n;
cin>>m;
for(int i=0; i<n; i++) {
double o=a(m);
if(o>max) {
max=o;
}
}
printf("%.2lf",max);
return 0;
}
```
