maxnum的初始化应该是最小的，题目数据从0到10，可能会有全部分数小于2的情况发生

两个if语句如果直接跳过的话很可能跳过多个而不是两个

n减了2而all很可能不是n-2个数的和

建议用个sum来记录和，用和减去最大值和最小值再除以n-2

代码：
```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
int n,ii,maxnum = 0,minnum = 11,sum = 0;
double all;
cin >> n;
for (int i = 0; i < n; i++){
cin >> ii;
if (ii > maxnum){
maxnum = ii;
}
if (ii < minnum){
minnum = ii;
}
sum += ii;
}
sum = sum - minnum - maxnum;
n -= 2;
all = (double) sum / n;
cout << fixed << setprecision(2) << all;
return 0;
}
```
