公共汽车订票系统C++

很抱歉，我无法访问和下载外部资源。但是我可以为您提供一个关于公共汽车订票系统的C++代码示例，以供参考。

以下是一个简单的公共汽车订票系统的C++代码示例：

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

class BusTicketSystem {
private:
    string busNumber;
    int totalSeats;
    int availableSeats;

public:
    BusTicketSystem(string number, int seats) {
        busNumber = number;
        totalSeats = seats;
        availableSeats = seats;
    }

    void displayBusDetails() {
        cout << "Bus Number: " << busNumber << endl;
        cout << "Total Seats: " << totalSeats << endl;
        cout << "Available Seats: " << availableSeats << endl;
    }

    void bookTicket(int numSeats) {
        if (numSeats <= availableSeats) {
            availableSeats -= numSeats;
            cout << "Ticket booked successfully!" << endl;
        } else {
            cout << "Not enough seats available." << endl;
        }
    }

    void cancelTicket(int numSeats) {
        if (numSeats <= (totalSeats - availableSeats)) {
            availableSeats += numSeats;
            cout << "Ticket cancelled successfully!" << endl;
        } else {
            cout << "Invalid number of seats to cancel." << endl;
        }
    }
};

int main() {
    BusTicketSystem bus("ABC123", 50);
    bus.displayBusDetails();

    bus.bookTicket(3);
    bus.displayBusDetails();

    bus.cancelTicket(2);
    bus.displayBusDetails();

    return 0;
}

这个示例代码创建了一个名为`BusTicketSystem`的类，用于管理公共汽车的订票系统。它包括了公共汽车的编号、总座位数和可用座位数等属性，以及显示公共汽车详情、预订票和取消票等方法。
