Answer 1

#include <iostream>
#include <cmath>
using namespace std;

double calc(double d)
{
    double money = 0.0;  
    if (d >= 10.0) {
        money += d * 1.8 * 1.5;
    }
    else {
        money += 3.0;
        if (d > 0 && d <= 1.0) {
            money += 0.0;
        }
        else if (d > 1.0 && d <= 1.5) {
            money += 4.0;
        }
        else if (d > 1.5 && d <= 2.0) {
            money += 5.0;
        }
        else if (d > 2.0 && d <= 2.5) {
            money += 6.0;
        }
        else if (d > 2.5 && d <= 3.0) {
            money += 7.0;
        }
        else {
            money += ceil(d - 3.0) * 1.8;
        }
    }
    money = ceil(money / 0.5) * 0.9;  
    return money;
}

int main() 
{
    double d;
    cout << "请输入公里数: ";
    cin >> d;
  
    double money = calc(d);
    cout << "车费为: " << money << " 元" << endl;

    return 0;
