```cpp
else if(a>150){
cout<<fixed<<setprecision(1)<<50*0.4463+(a-150)*0.4633;
}
```
这里应该是
```cpp
else if(a>150){
cout<<fixed<<setprecision(1)<<150*0.4463+(a-150)*0.4663;
}
```

```cpp
}else if(a>150){
cout<<fixed<<setprecision(1)<<50*0.4463+(a-150)*0.4633;
```
的 0.4633 是怎么回事？

两处数字打错了，手动模拟一下样例就能找到

//AC code: You'd better use "(double)(expression)" when it comes to "%.nf" of "printf". By the way, acquire the information above the code more cautiously next time.
eg:0.4633--0.4663. 50--150.//
```cpp
#include<iostream>
#include<iomanip>
```
using namespace std;
int main(){
double a,c;
cin>>a;
if(a>400){
c=(double)(150*0.4463+250*0.4663+(a-400)*0.5663);
printf("%.1f",c);
}else if(a>150){
c=(double)(150*0.4463+(a-150)*0.4663);
printf("%.1f",c);
}else{
c=(double)(0.4463*a);
printf("%.1f",c);
}
return 0;
}
