Problem D: 字符类的封装

Problem D: 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。

#include <iostream>

using namespace std;

class Character {
private:
    char ch;
public:
    Character() {
        cout << "Default constructor is called!" << endl;
    }
    Character(char c) {
        ch = c;
        cout << "Character "<<c<<" is created!" << endl;
    }
    void setCharacter(char c) {
        ch = c;
    }
    char getCharacter() { return ch; }
    int getAsciiCode() {
        int temp = (int)ch;
        return temp;
    }
    ~Character() {
        cout << "Character "<<ch<<" 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;
}
