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vehicle类，并派生出mot。rcar类和bicycle类。然后以mottorcar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：801501001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＜iostream．h＞class vehicle{private：int MaxSpeed；int Weight；public：／／**********found**********vehicle(intmaxspeed，intweight)：_______～vehicle(){}；int getMaxSpeed(){return MaxSpeed；}int getWeight(){return Weight；}}；／／**********found**********class bicycle：______________public vehicle{private：int Height；public：bicycle(int maxspeed，int weight，int height)：vehicle(maxspeed，weight)，Height(height){}int getHeight(){return 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**********classmotorcycle：______________{public：motorcycle(int maxspeed，int weight，int height)：vehicle(maxspeed，weight)，bicycle(maxspeed，weight，height)，motorcar(maxspeed，weight，1){}}；void main(){motorcycle a(80，150，10)；cout＜＜a．getMaxSpeed()＜＜endl；cout＜＜a．getWeight()＜＜endl；cout＜＜a．getHeight()＜＜endl；cout＜＜a．getSeatNum()＜＜endl；}
