```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
double sum = 0, n;
cin >> n;
if(n <= 150)
{
sum += n * 0.4463;
}
else if(n > 150 && n <= 400)
{
sum += 150 * 0.4463;
sum += (n - 150) * 0.4663;
}
else
{
sum += 150 * 0.4463;
sum += 250 * 0.4663;
sum += (n - 400) * 0.5663;
}
cout << fixed << setprecision(1) << sum;
return 0;
}
```
请大家看一下我的
我用的cout和setprecision(1)
