我写一段伪代码,没有经过编译器编译的:
class CPoint
{
public:
CPoint();
CPoint（x,y）{m_x -= x; m_y = y;};
void SetPos(int x, int y){m_x -= x; m_y = y;};
int GetX(){return m_x;};
int GetY(){return m_y;};
public:
int m_x,m_y;
}
class CLine : public CPoint
{
public：
CLine();
CLine(x,y);
int GetDistance();
}
CLine::CLine(x,y)
:CPoint(x,y)
{
}
int CLine::GetDistance()
{
return y-x;
}
class CRect : public CLine
{
public:
CRect(left, top, right, bottom);
int GetSize();
private:
CPoint m_leftTop;
CPoint m_rightBottom;
}
CRect::CRect(left, top, right, bottom)
：m_leftTop(left, top)
, m_rightBottom(right, bottom)
{
}
int CRect::GetSize()
{
return (m_rightBottom.y-m_leftTop.y)*(m_rightBottom.x - m_leftTop.x);
}
敲得累死了，没有经过编译编译，应该问题不大。
