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).
   // Define a class
   #include <iostream>
   using std::cout;
   using std::endl;
   
   class CBox                     // Class definition at global scope
   {
       double m_Length;           // Length of a box in inches
       double m_Width;            // Width of a box in inches
       double m_Height;           // Height of a box in inches
   };
   
   int main()
   {
     CBox box1;                   // Declare box1 of type CBox
   
     box1.m_Height = 18.0;        // Define the values
     box1.m_Length = 78.0;        // of the members of
     box1.m_Width = 24.0;         // the object box1 
   
     cout << "Volume of box1 = "
          <<  box1.m_Height*box1.m_Length*box1.m_Width
          << endl;
     return 0;
