new mistake class

[unidentify]

I create a CRealPoint class: CRealPoint { public: CRealPoint(); CRealPoint(double x=0; double y=0); private: double m_x; double m_y; public: CRealPoint operator=(CRealPoint rPt); } then I have following code: // 1. CArray m_arrPo; 2. CRealPoint tmpPoint; 3. tmpPoint.m_x= // calculate here 4. tmpPoint.m_y=// 5. m_arrPo.Add(tmpPoint); // 6. CRealPoint newPoint; 7. newPoint = m_arr.ElementAt(0); // test value of newPoint.m_x, newPoint.m_y It is lost data. I guess problem occur at line 5 or 7 but don't understand why and don't known how to solve this problem. don't stop me now!!!

change these lines 1. CArray <CRealPoint,CRealPoint&> m_arrPo; . . . 6 CRealPoint &newPoint = m_arr.ElementAt(0); // ElementAt return ref to ob or 6 CRealPoint newPoint = m_arr.GetAt(0); // GetAt return ob and need copy constructor that ur class have it. BTW. CRealPoint newPoint = m_arr.ElementAt(0); is also correct :)
