一个40的（不知道会不会被理）

@Iochi_YC 这是分段计费。

#include <bits/stdc++.h>
using namespace std;
int man;
int main() {
    cin>>man;
    if(man<=150){
         cout<<fixed<< setprecision(1)<<man*0.4463;
    }else if(man<=400){
         cout<<fixed<< setprecision(1)<<150*0.4463+(man-150)*0.4663;
    }else{
       cout<<fixed<< setprecision(1)<<150*0.4463+250*0.4663+(man-400)*0.5663;
    }
    return 0;
}

盖乐已瞎

#include <bits/stdc++.h>
using namespace std;
double bou = 0;
double man;
int main() {
    cin>>man;
    if(man >= 150){
        bou += 150 * 0.4463;
        man -= 150;
        if(man >= (400 - 150)){
            bou += 250 * 0.4663;
            man -= 250;
            if(man > 0){
                bou += man * 0.5663;
            }
        }
        else{
            bou += man *0.4663;
        }
    }
    else{
        bou += man *0.4463;
    }
    printf("%.1lf\n",bou);
    return 0;
}

本来想在你的基础上做改变，结果除了头文件和变量的定义没一个有用的，还有与运算时是&&不是||，这是你的主要问题

#include <bits/stdc++.h>
using namespace std;
double man;
int main() {
    cin>>man;
    if(man<=150){
        printf("%.1F",man*0.4463);
return 0;
    }
    if(man>=151&&man<=400){
        printf("%.1F",(man-150)*0.4663+150*0.4463);
return 0;
    }
    if(man>=401){
        printf("%.1F",(man-400)*0.5663+250*0.4663+150*0.4463);
return 0;
    }

    return 0;
}
