Question

请大神帮助编辑一个C++ 设计一个程序，定义一个汽车类Vehicle,它具有一个需要传递参数的构造函数，

类中的数据包括：车轮个数wheel和车重weight，两者作为保护成员；小车类Car是它的私有派生类，其中包括承载人数passengers;卡车类Truck是Vehicle的私有派生类，其中包括承载人数passengers和载重量payload。每个类都有相关数据的输出方法。

Answer 1

class Vehicle
{
protected:
    int wheels;
    float weight;
public:
    Vehicle(int wh, float we): wheels(wh), weight(we) {}
    void display();
    int getWheels();
    float getWeight();
};
class Car: private Vehicle
{
private:
    int passengers;
public:
    Car(int wh, float we, int pa): Vehicle(wh, we), passengers(pa) {}
    int getPassengers();
    void display();
};
void Car::display()
{
    cout << "wheels: " << wheels << endl;
    cout << "weight: " << weight << endl;
    cout << "passengers: " << passengers << endl;
}
class Trunk: private Vehicle
{
private:
    float payload;
    int passengers;
public:
    Trunk(int wh, float we, int pay, int pas): Vehicle(wh, we), payload(pay), passengers(pas) {}
    float getPayload();
    int getPassengers();
    void display();
};
