   #include <iostream>
   using std::cout;
   
   class CNumber
   {
   public:
           CNumber(int v)
           {
                   cout << "A number is created with value: " << (m_value = v)
                           << "\n";
           }
   
           ~CNumber()
           {
                   cout << "The object containing " << m_value
                           << " is destroyed.\n";
           }
   
       int m_value;
   };
   
   int main()
   {
           CNumber a(1);
           CNumber* pv1 = new CNumber(2);
           CNumber* pv2 = new CNumber(3);
           cout << "The value of m_value is " << *pv2.m_value << "\n";
   }
   
   
   
   
   
   
   

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