   // Ex7_01A.cpp
   #include <iostream>
   #include <windows.h>
   
   int main()
   {
   	RECT aRect = { 0, 0, 100, 100 };
   	RECT* pRect = &aRect;
   
   	pRect.top += 10;
   
   	std::cout << pRect.top;
   }
   
       

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).

   // Ex7_01B.cpp
   #include <iostream>
   #include <windows.h>
   
   struct ListElement
   	{
   		int value;
   		ListElement* pNext;
   	}
   
   int main()
   {
   	ListElement L1 = { 1 };
   	L1.pNext = NULL;
   	std::cout << L1.value << std::endl;
   }
   
   
   
   

3. (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).

   // Ex7_01C.cpp
   #include <iostream>
   #include <windows.h>
   
   struct ListElement
   	{
   		int value;
   		ListElement* pNext;
   	};
   
   int main()
   {
   	ListElement L1 = { 1 }; 
   	ListElement L2 = { 2 }; 
   	ListElement L3 = { 3 }; 
   	L1.pNext = &L2;
   	L2.pNext = &L3;
   	L3.pNext = NULL;
   	ListElement* p = &L1;
   	while (p != NULL) 
   	{
   		std::cout << p->value << std::endl;
   		p = p->pNext;
   	}
   }
