   class Sample
   {
   public:
   	int i;
   	int j;
   	char* sPtr;
   }
   
   int main()
   {
   	Sample a, b;
   	a.i = 1;
   	a.j = 2;
   	a.sPtr = "Hello, World!";
   	b = a;
   	cout << b.sPtr << endl;
   }
   
      

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).

   struct ListElement
   	{
   		int value;
   		ListElement* pNext;
   	};
   
   int main()
   {
   	ListElement L1 = { 1 }; 
   	ListElement L2 = { 2 }; 
   	ListElement L3 = { 3 }; 
   	L1.pNext = NULL;
   	L2.pNext = &L1;
   	L3.pNext = &L2;
   	ListElement* p = &L2;
   	while (p != NULL) 
   	{
   		std::cout << p->value << std::endl;
   		p = p->pNext;
   	}
   }
