Problem B: 字符类的封装

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!

HINT

Append Code

#include<iostream>

using namespace std;

class Character

{

private:

    char ch;

public:

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

    Character(char c){ch=c;cout<<"Character a is created!\n";}

    void setCharacter(char c){ch=c;}

    int getAsciiCode(){return ch;}

    char getCharacter(){return ch;}

    ~Character(){cout<<"Character "<<ch<<" is erased!\n";}

};

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;

}
