请使用“答题”菜单或使用VC6打开考生文件夹proj2下的工程proj2，其中定义了vehicle类，并派生出motorcar类和bicycle类。然后以motocar和bicycle作为基类，再派生出motocycle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，然后删除横线，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，也不能删除或移动“／／**********found**********”。#include＜iostream．h＞classvehicle{private：intMaxSpeed；intWeight；public：／／**********found**********vehicle(intmaxspeed，intweight)：________________~vehicle(){}；intgetMaxSpeed(){returnMaxSpeed；}intgetWeight(){returnWeight；}}；／／**********found**********classbicycle：________publicvehicle{private：intHeight；public：bicycle(intmaxspeedlintweight，intheight)：vehicle(maxspeed，weight)，Height(height){}intgetHeight(){returnHeight；}；}；／／**********found**********classmotorcar：________publicvehicle{private：intSeatNum；public：motorcar(intmaxspeed，intweight，intseatnum)：vehicle(maxspeed，weight)，SeatNum(seatnum){)intgetSeatNum(){returnSeatNum；}；}；／／**********found**********classmotorCyCle：________{public：motorcycle(intmaxspeed，intweight，intheight)：vehicle(maxspeed，weight)，bicycle(maxspeed，weight，height)，motorcar(maxspeed，weight，1){}}；voidmain(){motorcyclea(8．0，150，100)；cout＜＜a．getMaxSpeed()＜＜end1；cout＜＜a．getWeight()＜＜end1；cout＜＜a．getHeight()＜＜end1；cout＜＜a．getSeatNum()＜＜end1；}
