如何创建一个类，该类将根据用户输入三条路线、3 条出发时间和 3 条到达时间后根据他们想要离开的时间获取有关最佳路线的信息

我已经尝试了下面的代码，但我现在被困住了.我知道，我必须做一些如果陈述可能..

#include <iostream>
#include <string>
class route {
private:
std::string name_;
int departure_time_;
int arrival_time_;
public:
void set_name(std::string name) {
name_ = name;
}
void set_departure_time(int deparure_time) {
departure_time_ = deparure_time;
}
void set_arrival_time(int arrival_time) {
arrival_time_ = arrival_time;
}
};
void route1 () {
std::string name;
int departure;
int arrival;
std::cout << "Route 1:n";
std::cout << "Please enter the name of the route: ";
std::getline(std::cin, name);
std::cout << "Please enter the departure time of the route: ";
std::cin >> departure;
std::cout << "Please enter the arrival time of the route: ";
std::cin >> arrival;
}
void route2 () {
std::string name;
int departure;
int arrival;
std::cout << "Route 2:n";
std::cout << "Please enter the name of the route: ";
std::getline(std::cin, name);
std::cout << "Please enter the departure time of the route: ";
std::cin >> departure;
std::cout << "Please enter the arrival time of the route: ";
std::cin >> arrival;
}
void route3() {
std::string name;
int departure;
int arrival;
std::cout << "Route 3:n";
std::cout << "Please enter the name of the route: ";
std::getline(std::cin, name);
std::cout << "Please enter the departure time of the route: ";
std::cin >> departure;
std::cout << "Please enter the arrival time of the route: ";
std::cin >> arrival;
}
int main() {
int time_leaving;
std::cout << "Welcome to TuffyTravel!n";
route1();
std::cin.ignore();
route2();
std::cin.ignore();
route3();
std::cout << "Please enter the time you wish to leave: ";
std::cin >> time_leaving;
}

结果应该根据他们想要离开的时间给出最佳路线

这可能是您正在寻找的一些代码：

#include <iostream>
#include <string>
#include <vector>
struct Route {
std::string name;
int departure_time;
int arrival_time;
};
Route get_route (std::string prompt) {
Route route;
std::cout << prompt << std::endl;
std::cout << "Please enter the name of the route: ";
std::cin >> route.name;
std::cout << "Please enter the departure time of the route: ";
std::cin >> route.departure_time;
std::cout << "Please enter the arrival time of the route: ";
std::cin >> route.arrival_time;
return route;
}
int main() {
int time_leaving;
std::cout << "Welcome to TuffyTravel!n";
Route route1 = get_route("Route 1");
Route route2 = get_route("Route 2");
Route route3 = get_route("Route 3");
std::cout << "Please enter the time you wish to leave: ";
std::cin >> time_leaving;
std::vector<Route> routes_vec { route1, route2, route3 };
// Now find the best route in routes_vec
return 0;
}

请注意，它不会在routes_vec中找到最佳路线，也不会在用户输入不是出发或到达时间数字的情况下执行任何错误处理。
