c++ - How to fix this problem

Question

Code:

// 获取面积和周长
double      getArea()
{
    return sqrt((m_posLeftTop.getX - m_posRightBottom.getX)*(m_posLeftTop.getX - m_posRightBottom.getX)*(m_posLeftTop.getY - m_posRightBottom.getY)*(m_posLeftTop.getY - m_posRightBottom.getY));
}
double      getCircumference()
{
    return (fabs(m_posLeftTop.getX - m_posRightBottom.getX) + fabs(m_posLeftTop.getY - m_posRightBottom.getY)) * 2;
}

Answer 1

m_posLeftTop.getX()

Answer 2

I’m not sure about your code.

If m_posLeftTop is a pointer, change it to m_posLeftTop->getX
If getX is a method, change it to m_posLeftTop.getX()
If it is both of the above, change it to m_posLeftTop->get()
