Check whether the following program has any mistake. If yes, point out
the mistakes and correct them; if no, predict the output of the program.

#include <iostream>
#include <windows.h>

int main()
{
	RECT aRect = { 0, 0, 100, 100 };
	RECT* pRect = &aRect;

	pRect.top += 10;

	std::cout << pRect.top;
}

<LI> Determine whether the following code has syntax erros or not.  If
it is correct, predict its output.  If it is incorrect, point out the
mistake(s).


#include <iostream>
using std::cout;

class CNode
{
public:
    int data;
    CNode* next;

    CNode(int n, CNode* p);
};

int main()
{
    CNode c(3, NULL);
    CNode b(2, &c);
    CNode a(1, &b);

    CNode* p = &a;
    while (p != NULL)
    {
        cout << a.data << "\n";
	p = p->next;
    }
}
    
CNode::CNode(int n, CNode* p)
{
    data = n;
    next = p;
}
