C++ 交通工具（多重继承）

题目描述
1、建立如下的类继承结构：

1)一个车类CVehicle作为基类，具有max_speed、speed、weight等数据成员，display()等成员函数

2)从CVehicle类派生出自行车类CBicycle，添加属性：高度height

3)从CVehicle类派生出汽车类CMotocar，添加属性：座位数seat_num

4)从CBicycle和CMotocar派生出摩托车类CMotocycle

2、分别定义以上类的构造函数、输出函数display及其他函数（如需要）。

3、在主函数中定义各种类的对象，并测试之，通过对象调用display函数产生输出。

输入
第一行：最高速度 速度 重量
第二行：高度 第三行：座位数

输出
第一行：Vehicle:
第二行及以后各行：格式见Sample

样例输入
100 60 20
28
2
样例输出
Vehicle:
max_speed:100
speed:60
weight:20

Bicycle:
max_speed:100
speed:60
weight:20
height:28

Motocar:
max_speed:100
speed:60
weight:20
seat_num:2

Motocycle:
max_speed:100
speed:60 weight:20
height:28
seat_num:2

#include<iostream>
using namespace std;
class CVehicle{protected:int max_speed;int speed;int weight;public:CVehicle(){}CVehicle(int m,int s,int w){max_speed=m;speed=s;weight=w;}void displayCVehicle(){cout<<"Vehicle:"<<endl;cout<<"max_speed:"<<max_speed<<endl;cout<<"speed:"<<speed<<endl;cout<<"weight:"<<weight<<endl;}
};
class CBicycle:public CVehicle{protected:int height;public:CBicycle(int m,int s,int w,int h):CVehicle(m,s,w),height(h){}void displayCBicycle(){cout<<"Bicycle:"<<endl;cout<<"max_speed:"<<max_speed<<endl;cout<<"speed:"<<speed<<endl;cout<<"weight:"<<weight<<endl;cout<<"height:"<<height<<endl;}};
class CMotocar:public CVehicle{protected:int seat_num;public:CMotocar(int m,int s,int w,int s_n):CVehicle(m,s,w),seat_num(s_n){}void displayCMotocar(){cout<<"Motocar:"<<endl;cout<<"max_speed:"<<max_speed<<endl;cout<<"speed:"<<speed<<endl;cout<<"weight:"<<weight<<endl;cout<<"seat_num:"<<seat_num<<endl;}
};
class CMotocycle:public CMotocar,public CBicycle{public:CMotocycle(int m,int s,int w,int h,int s_n):CMotocar(m,s,w,s_n),CBicycle(m,s,w,h){}void displayCMotocycle(){cout<<"Motocycle:"<<endl; cout<<"max_speed:"<<CMotocar::max_speed<<endl;//详细见下文cout<<"speed:"<<CMotocar::speed<<endl;cout<<"weight:"<<CMotocar::weight<<endl;cout<<"height:"<<CBicycle::height<<endl;cout<<"seat_num:"<<CMotocar::seat_num<<endl;}
};
int main(){int m_s,s,w,h,s_n;cin>>m_s>>s>>w>>h>>s_n;CVehicle c1(m_s,s,w);c1.displayCVehicle();cout<<endl;CBicycle c2(m_s,s,w,h);c2.displayCBicycle();cout<<endl;CMotocar c3(m_s,s,w,s_n);c3.displayCMotocar();cout<<endl;CMotocycle c4(m_s,s,w,h,s_n);c4.displayCMotocycle();
}

Motocycle类继承了Motocar和Bicycle类，这两个父类同时拥有max_speed,speed,weight的数据成员，如果直接输出则分不清是Motocar还是Bicycle类的数据成员，需要告诉计算机具体的范围
