@[zappler](/user/555075) 再看一遍题目吧，你题目理解错了

@[Saint_ying_xtf](/user/852144) 不就是求出电费吗

现在哪里错了
```cpp
#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
int n;
cin >> n;
double m = 0;
if(n <= 150) m = 0.4463 * n;
else if(n >= 151 && n <= 400) m = 0.4663 * n;
else m = n * 0.5663;
cout << setprecision(1) << m << endl;
return 0;
}
```

@[zappler](/user/555075) 要分段计费
by Loser_Syx @ 2023-01-22 14:32:31
@[zappler](/user/555075) 不是说了分段计费？

@[Enoch006](/user/538683) @[Saint_ying_xtf](/user/852144) 所以呢 哪里错了

你这叫分段计费？类似于这种的才叫！
```cpp
b=0.4463*150+0.4663*250+(k-400)*0.5663;
```

@[zappler](/user/555075) 就是分成3个类别啊，你数学上没学过吗
