Description

定义Vehicle类,包括:

1. 一个int类型属性num,表示汽车的轮子数量。

2. 构造函数、析构函数,输出如样例所示的信息。

定义Bus类,是Vehicle类的子类,包括:

1. 一个int类型属性guest,表示客车可乘坐的人数。

2. 构造函数、析构函数,输出如样例所示的信息。

定义Truck类,是Vehicle类的子类,包括:

1. 一个int类型属性weight,表示货车可载荷的货物重量。

2. 构造函数、析构函数,输出如样例所示的信息。

 

Input

输入有多行,每行一个测试用例,每行包括1个正整数(车的轮子数量)、1个字符b或者t(b、t分别表示客车、货车)、1个正整数(可乘坐的人数或可承载的货物重量)。

 

Output

见样例。

 

Sample Input

4 b 408 t 15

Sample Output

Vehicle has 4 wheels is created.Bus which can carry 40 persons is created.Bus which can carry 40 persons is erased.Vehicle has 4 wheels is erased.Vehicle has 8 wheels is created.Truck which can carry 15 tons goods is created.Truck which can carry 15 tons goods is created.Vehicle has 8 wheels is erased.
