c++的编程题基础好的高手帮帮忙！

2、定义一个车（vehicle）基类，具有MaxSpeed、Weight等成员变量，Run、Stop等成员函数，由此公有派生出自行车（bicycle）类、汽车（motorcar）类。自行车（bicycle）类有高度（height）等属性，汽车（motorcar）类有座位数（SeatNum）等属性。从bicycle和motorcar公有派生出摩托车（motorcycle）类，把vehicle设置为虚基类
include <iostream.h>
class vehicle
{
private:
int maxspeed;
int weight;
public:
void run(){cout<<"maxspeed"<<endl;}
void stop(){cout<<"weight"<<endl;}
};
class biycle:virtual public vehicle
{
private:
int height;
public:
void yy(){cout<<"height"<<run()<<stop()<<endl;}
};
class motorcar:virtual public vehicle
{
private:
int seatsum;
public:
void yy1(){cout<<"seatsum"<<run()<<stop()<<endl;}
};

class motorcycle:public biycle,public motorcar
{
public:
void yy2();
};
void motorcycle::yy2()
{
yy();
yy1();
}
void main()
{
motorcycle c;
c.yy2();
}
请按照题目，把我的程序改一下，并解释一下！要用我提到的函数做，别自己加函数和变量！
并且解释一下，这几句话什么意思！
c:\documents and settings\yinyue\桌面\cpp1.cpp(1) : error C2143: syntax error : missing ';' before '<'
c:\documents and settings\yinyue\桌面\cpp1.cpp(1) : error C2501: 'include' : missing storage-class or type specifiers

c:\documents and settings\yinyue\桌面\cpp1.cpp(19) : error C2504: 'vehicle' : base class undefined
先给10分，答的好我加分！
我调用run()和stop()是为了输出maxspeed，weight

#include <iostream.h>
class vehicle
{
private:
int maxspeed;
int weight;
public:
void run()
{
cout<<"maxspeed"<<endl;
}
void stop()
{
cout<<"weight"<<endl;
}
};
class biycle:virtual public vehicle
{
private:
int height;
public:
void yy()
{
cout<<"height"<<endl;//修改的地方
run();
stop();
}
};
class motorcar:virtual public vehicle
{
private:
int seatsum;
public:
void yy1()
{
cout<<"seatsum"<<endl;//修改的地方
run();
stop();
}
};

class motorcycle:public biycle,public motorcar
{
public:
void yy2();
};
void motorcycle::yy2()
{
yy();
yy1();
}

int main()
{
motorcycle c;
c.yy2();
return 0;
}

你的include 没有#，而且cout输出变量值，run()，stop（）没有返回值，不能用cout输出本回答被提问者采纳
