Description

先来个简单习题，练练手吧！现在需要你来编写一个Character类，将char这一基本数据类型进行封装。该类中需要有如下成员函数：

1. 无参构造函数。

2. 构造函数Character(char)：用参数初始化数据成员。

3. void setCharacter(char)：重新设置字符值。

4. int getAsciiCode()：返回字符的ASII码。

5. char getCharacter()：返回字符值。

6. 析构函数。

Input

输入只有1行，包含一个合法的、可打印的字符。

Output

输出有好多行，请参考样例来编写相应的函数。

Sample Input

c

Sample Output

Default constructor is called!Character a is created!ch1 is c and its ASCII code is 99.ch2 is a and its ASCII code is 97.Character a is erased!Character c is erased!

private :

     char x_;

public :

     Character(){cout<< "Default constructor is called!" <<endl;}

     Character( char x):x_(x){cout<< "Character a is created!" <<endl;}

     void setCharacter( char x){ x_=x;}

     int getAsciiCode(){ return x_;}

     char getCharacter(){ return x_;}

     ~Character(){cout<< "Character " <<x_<< " is erased!" <<endl;}

};

int main()

{

     char ch;

     Character ch1, ch2( 'a' );

     cin>>ch;

     ch1.setCharacter(ch);

     cout<< "ch1 is " <<ch1.getCharacter()<< " and its ASCII code is " <<ch1.getAsciiCode()<< "." <<endl;

     cout<< "ch2 is " <<ch2.getCharacter()<< " and its ASCII code is " <<ch2.getAsciiCode()<< "." <<endl;

     return 0;
