结构数组的赋值

void CGraphicDemoView::OnMouseMove(UINT nFlags, CPoint point)
{
POINT Point[] = {-59, -81, 0, 100, 59, -81, -95, 31, 95, 31};
// 这样是怎么赋值的？
//Point 是一个结构，有两个变量，数组赋值时两个变量同时也赋值了？

 for(int i=0; i<5; i++)
 {
  Point[i].x += point.x;
  Point[i].y += point.y;
 }
 CBrush Brush( RGB((rand() & 0xff), (rand() & 0xff), (rand() & 0xff)));

 CPen Pen(PS_SOLID,1, RGB((rand() & 0xff),(rand() & 0xff),(rand() & 0xff)));

 CClientDC ClientDC(this);

 CBrush *pOldBrush = (CBrush*)ClientDC.SelectObject(&Brush);
 CPen *pOldPen = (CPen*)ClientDC.SelectObject(&Pen);

 CRgn Rgn;
