程序的运行结果为:
the wheel of vehicle is : 0
the weight of vehicle is : 0
the num of train is : 0
the weight of train is : 0
the Passengers of train is : 0
the num of train is : 10
the weight of train is : 100
the Passengers of train is :100
the wheel of car is : 4
the weight of car is : 2
the Passengers of car is : 4
