1. (10%) If we replace the OnDraw() function in P.953 as below, what result will be shown on the screen after you run the program?  Please specify the coordinates of endpoints of each segment.

   void CSketcherView::OnDraw(CDC* pDC)
   {
   	CSketcherDoc* pDoc = GetDocument();
   	ASSERT_VALID(pDoc);
   	if (!pDoc)
   		return;
   
   	for (int i=0; i<5; i++)
   		pDC->Rectangle(i*10, i*10, 90-i*10, 90-i*10);
   }
