Description

一切都是对象 —— Everything is an object。 所以,现在定义一个类Thing,来描述世界上所有有名字的事物。该类只有构造函数、拷贝构造函数和析构函数,并具有一个字符串数据成员来存储其名字。

Input

输入只有1行,是一个没有空白符的字符串。

Output

见样例。

Sample Input

NAME

Sample Output

A thing without name is created!
A thing without name is copied!
A thing named by NAME is created!
A thing named by NAME is copied!
A thing named by NAME is erased!
A thing named by NAME is erased!
A thing without name is erased!
A thing without name is erased!

HINT

Append Code

append.cc, 、
int main() 
{ 
    string name; 
    Thing Thing1, Thing2(Thing1); 
    cin>>name; 
    Thing Thing3(name); 
    Thing Thing4(Thing3); 
    return 0; 
}

代码如下:
#include  
#include  
#include  
#include 
using namespace std; 
class Thing 
{ 
private: 
    string name; 
public: 
    Thing() 
    { 
        name = "without name"; 
        cout<<"A thing without name is created!"<>name; 
    Thing Thing3(name); 
    Thing Thing4(Thing3); 
    return 0; 
}
