   using std::endl;
   using std::cout;
   
   class CData
   {
       public:
           int* pdata;
   
       CData(int n=0)
       {
           pdata = new(int);
           *pdata = n;
           cout << "Constructor called with initial value " << n << endl;
       }
   
       ~CData()
       {
           cout << "Destructor called to release the memory storing "
                   << *pdata << endl;
           delete pdata;
       }
   };
   
   
   int main()
   {
       CData a(3);
       CData b;
       CData c(8);
       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).
   // Function Overloading (P.310)
   #include <iostream>
   
   int pdo_it(int a, int b, int c)
   { return a + b + c; }
   
   int pdo_it(int a, int b)
   { return a * b; }
   
   int main()
   {
       std::cout << pdo_it(3, 8) << std::endl;
       std::cout << pdo_it(2013, 3, 8) << std::endl;
       std::cout << pdo_it( pdo_it(20,13), 13, 18 ) << std::endl;
       return 0;
   }
