Problem B: 字符類的封裝

Description

先來個簡單習題，練練手吧！現在需要你來編寫一個Character類，將char這一基本數據類型進行封裝。該類中需要有如下成員函數：

1. 無參構造函數。

2. 構造函數Character(char)：用參數初始化數據成員。

3. void setCharacter(char)：重新設置字符值。

4. int getAsciiCode()：返回字符的ASII碼。

5. char getCharacter()：返回字符值。

6. 析構函數。

Input

輸入只有1行，包含一個合法的、可打印的字符。

Output

輸出有好多行，請參考樣例來編寫相應的函數。

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;
