我直接给你我的代码吧

我没实力，但我可以保证我的代码比楼上（下）好一点点（不是“亿”），给朋友看会显得你比较帅，会很多东西

#include <bits/stdc++.h>
using namespace std;
int a;
double price = 0.0;
double dian1(int x);
double dian2(int x);
double dian3(int x);
void print(double x);
int main(){
    scanf("%d",&a);
    if(a<=150)print(dian1(a));
    else if(a>150 && a<=400)print(dian2(a));
    else print(dian3(a));
    return 0;
}
double dian1(int x){
    price+=x*1.0*0.4463;
    return price;
}
double dian2(int x){
    price+=1.0*0.4463*150+(x-150)*1.0*0.4663;
    return price;
}
double dian3(int x){
    price+=1.0*0.4463*150+(400-150)*1.0*0.4663+(x-400)*1.0*0.5663;
    return price;
}
void print(double x){
    printf("%.1lf",x);
    return;
}
