```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int st,ju,maxn=0,ju1[1001],minn=101;
double sum[1001],big;
cin >> st >> ju;
for(int i=0;i<st;i++)
{
for(int j=0;j<ju;j++)
{
cin >> ju1[j];
sum[i]+=ju1[j];
if(ju1[j]>maxn)maxn=ju1[j];
if(ju1[j]<minn)minn=ju1[j];
}
sum[i]=(sum[i]-maxn-minn)/(ju-2); //此处
if(sum[i]>sum[i-1])
big=sum[i];
else
continue;
maxn=0,minn=101;
}
printf("%.2lf",big);
return 0;
}
```
我注释的地方有问题，C++默认整数除以整数会向下取整，所以在这个表达式前面要加上1.0* ，即sum[i]=1.0*(sum[i]-maxn-minn)/(ju-2)
