1. (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).
   // Access Control
   #include <iostream>
   
   class CBox           // Class definition at global scope
   {
   private:
       int m_Length;    // Length of a box in inches
       int m_Width;     // Width of a box in inches
       int m_Height;    // Height of a box in inches
   
       CBox(int lv, int wv, int hv)    // Constructor
       {
           m_Length = lv;
           m_Width = wv;
           m_Height = hv;
       }
   
       int Volume()
       {
           return m_Length * m_Width * m_Height;
       }
   };
   
   int main()
   {
     CBox box1(1, 2, 3);   // Declare box1 of type CBox
     std::cout << box1.Volume() << 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).
   // Copy Constructor
   #include <iostream>
   
   class CBox              // Class definition at global scope
   {
   public:
       int m_Length;       // Length of a box in inches
       int m_Width;        // Width of a box in inches
       int m_Height;       // Height of a box in inches
   
       CBox(int lv, int wv, int hv)    // Constructor
       {
           m_Length = lv;
           m_Width = wv;
           m_Height = hv;
       }
   
       CBox(const CBox& aBox)   // Copy Constructor
       {
           m_Length = aBox.m_Length;
           m_Width  = aBox.m_Width;
           m_Height = aBox.m_Height * 2;
       }
   
       int Volume()
       {
           return m_Length * m_Width * m_Height;
       }
   };
   
   int main()
   {
     CBox box1(1, 2, 3);     // Declare box1 of type CBox
     CBox box2 = box1;       // Declare box2 of type CBox
     std::cout << box2.Volume() << std::endl;
     return 0;
   }
