    // Inheritance
    #include <iostream>

    class CBox
    {
    public:
    	int m_Length;
    	int m_Width;
    	int m_Height;

    	CBox(int lv = 1, int wv = 2, int hv = 3): m_Length(lv), m_Width(wv), m_Height(hv) {}
    	int Volumn() { return m_Length * m_Width * m_Height; }
    };

    class CCandyBox: public CBox
    {
    public:
    	char m_Contents[12];
    	CCandyBox(const char *str = "Candy")
    	{
    		strcpy(m_Contents, str);
    	}
    };

    int main()
    {
    	CCandyBox myCandyBox("Chocolate");	
    	std::cout << sizeof(CBox) << std::endl;
    	std::cout << sizeof(myCandyBox) << std::endl;	
    	return 0;
    }



  2. (10%) Determine whether the following code has syntax errors or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).

    protected:
    	int m_Length;
    	int m_Width;
    	int m_Height;

    	CBox(int lv = 1, int wv = 2, int hv = 3): m_Length(lv), m_Width(wv), m_Height(hv) {}
    	int Volumn() { return m_Length * m_Width * m_Height; }
    };

    public:
    	CCandyBox(const char *str = "Candy")
    	{
    		strcpy(m_Contents, str);
    		std::cout << "Construct a CandyBox " << str << " with volume "
    			<< m_Length * m_Width * m_Height << std::endl;
    	}
    };
