@[yangzijun0530](/space/show?uid=236071) 您的一个else的大括号放错位置了, 应该包含另外两个if
帮您改的代码:
```c
#include <iostream>
using namespace std;
int main(){
int a;
double b;
cin>>a;
if(a<=150){
b=a*0.4463;
}
else{
if(a<=400){
b=150*0.4463+(a-150)*0.4663;
}
else{
b=150*0.4463+(250*0.4663)+((a-400)*0.5663);
}
}
cout<<int((b*10)+0.5)/10.0; return 0;
}
```
