请帮忙看一下为什么会错，谢谢。

@yhdxg

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,a[1001],maxn=0,minn=INT_MAX;
    double h=0;
    cin>>n;
    for(int i=1;i<=n;i++){
        cin>>a[i];
        h+=a[i];
        maxn=max(maxn,a[i]);
        minn=min(minn,a[i]);
    }
    cout<<fixed<<setprecision(2)<<(h-maxn-minn)*1.0/(n-2)<<endl;
}

1.数组开小了

2.找最大最小值无需再加一层循环,直接在输入时就行了

3.minn应该定义成最大值

4.输出时应转化成double,乘一个1.0

@yhdxg 全改成double，你个整数类型除以个double类型？
