Question

定义一个车类(Vehicle)基类,具有MaxSpeed,Weight成员变量,run(),stop(),构造函数,～～～～

C++： 定义一个车类（Vehicle）基类，具有MaxSpeed,Weight成员变量，run(),stop()，构造函数等成员函数，由此派生出自行车（Bicycle）类，汽车（Motorcar）类。自行车类有高度（Height）属性，汽车类有座位（SeatNum）属性。

Answer 1

#include<iostream.h>
class vehicle
{
protected:
int MaxSpeed;
int Weight;
public:
vehicle(int s,int w){MaxSpeed=s;Weight=w;}
void SetMaxSpeed(int s){MaxSpeed=s;}
void SetWeight(int w){Weight=w;}
void Run(){cout<<"class vehicle is running!"<<endl;}
void Stop(){cout<<"class vehicle has stopped!"<<endl;}
};

class bicycle:virtual public vehicle
{
protected:
int Height;
public:
bicycle(int h,int s,int w):vehicle(s,w)
{Height=h;}
};

class motorcar:virtual public vehicle
{
protected:
int SeatNum;
public:
motorcar(int S,int s,int w):vehicle(s,w)
{SeatNum=S;}
};

class motorcycle:public bicycle,public motorcar
{

public:
motorcycle(int s,int w,int h,int S):vehicle(s,w),bicycle(h,s,w),motorcar(S,s,w){}
void Show()
{
cout<<"MaxSpeed:"<<MaxSpeed<<endl;
cout<<"Weight:"<<Weight<<endl;
cout<<"Height:"<<Height<<endl;
cout<<"SeatNum:"<<SeatNum<<endl;
}
};
void main()
{
motorcycle mc(150,200,15,3);
mc.Show();
}
