@[yhdxg](/user/1050431) 您的尖括号输入有问题且少了一半，```for```循环中一个分号打成了逗号。

`#include＜bits/stdc++.h>`你第一行

还有导入的头文件应该是```bits/stdc++.h```而不是```bius/std++. h```

```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
int a[101][21],n,m,maxx,minn;
cin>>n>>m;
for(int i=1;i<=n;i++){
maxx=-1;minn=11;
for(int j=1;j<=m;j++){
cin>>a[i][j];
if(maxx<a[i][j])
maxx=a[i][j];
if(minn>a[i][j])
minn=a[i][j];
a[i][0]+=a[i][j];
}
a[i][0]-=maxx+minn;
}
maxx=0;
for(int i=1;i<=n;i++){
if(maxx<a[i][0])
maxx=a[i][0];
}
cout<<fixed<<setprecision(2)<<double(maxx/2)<<endl;
return 0;
}
```
