你的最后一个else语句中
n+=0.4663*(a-150);
有一点问题
两种解决方法
1.将(a-150)换成250
2.将（a-150)换成（a-150-400)

```
#include<bits/stdc++.h>
using namespace std;
double a,b,sum;
int main(){
cin>>a;
b=a;
if(a<=150){
sum=sum+a*0.4463;
}
else if(a<=400 and a>=151){
sum=sum+(a-150)*0.4663+150*0.4463;
}
else{
sum=sum+(a-400)*0.5663;
sum=sum+250*0.4663;
sum=sum+150*0.4463;
}
cout<<fixed<<setprecision(1)<<sum;
return 0;
}
```
AC代码，不喜勿喷
