   // Size of a struct
   #include <iostream>
   struct RECT
   {
       long    left;
       long    top;
       long    right;
       long    bottom;
   };
   
   struct ListElement       
   {
       RECT aRect;     // P.361      
       ListElement* pNext;
   };
   
   
   int main()
   {
       std::cout << sizeof(ListElement) << std::endl;
       return 0;
   }
   
   
   
2. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
