问答题 请使用VC6或使用【答题】菜单打开考生文件夹proj2下的工程proj2,其中定义了vehiele类,并派生出motorcar类和bicycle类。然后以motorcar和bicycle作为基类,再派生出motorcycle类。要求将Vehicle作为虚基类,避免二义性问题。请在程序中的横线处填写适当的代码并删除横线,以实现上述类定义。此程序的正确输出结果应为: 80 150 100 1 注意:只能在横线处填写适当的代码,不要改动程序中的其他内容,也不要删除或移动“//****found****”。 #include class vehicle { private: int MaxSpeed; int Weight; public: //*************found************ vehicle(int maxspeed,int weight):—— ~vehicle(){}; int getMaxSpeed(){return MaxSpeed;} int getWeight(){retum Weight;} }; //****************found************ class bicycle:——public vehicle { private: int Height; public: bicycle(int maxspeed,int weight,int height):vehicle(maxspeed,weight),Height(height){} int getHeight(){retum Height;}; }; //*******************found************** class motorcar:——public vehicle { private: int SeatNum; public: motorcar(int maxspeed。int weight,int seatnum):vehicle(maxspeed,weight),SeatNum(seatnum){} int getSeatNum(){return SeatNum;}; }; //*****************found*************** class motorcycle:—— { public: motorcycle(int maxspeed,int weight,int height):vehicle(maxspeed,weight),bicycle(maxspeed,weight, height),motorcar(maxspeed,weight,1){} }; void main() { motorcycle a(80,150,100); cout<
【正确答案】(1)MaxSpeed(maxspeed),Weight(weight){f; (2)virtual (3)virtua1 (4)public bicycle,public motorcar
