C++实例练习：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:20Bicycle:
max_speed:100
speed:60
weight:20
height:28Motocar:
max_speed:100
speed:60
weight:20
seat_num:2Motocycle:
max_speed:100
speed:60
weight:20
height:28
seat_num:2
