2. The OS will also move memory from and to hard disk as needed in order to keep
the entire system running smoothly. Repeatedly. At runtime! Again, you cannot
influence that short of rewriting the OS

CString ftitle;

fscanf_s(f_ptr_seed_inf,"%s\n",ftitle.GetBuffer(MAX_PATH));

ftitle.ReleaseBuffer();

What is the use of abstract class ?

class Shape
{
public:
    Shape( int nWidth, int nHeight )
    {
        m_nWidth  = nWidth;
        m_nHeight = nHeight;
    }

    virtual double getArea() = 0; // can't derive from directly

protected:
    int m_nWidth;
    int m_nHeight;
};

//====================================================================

class Circle : public Shape
{
public:
    Circle( int nWidth, int nHeight ) : Shape(nWidth, nHeight) {};

    double getArea() 
    {
        int nRadius = m_nWidth / 2;
        return 3.1415962 * nRadius * nRadius;
    }
};

//====================================================================

class Square : public Shape 
{
public:
    Square( int nWidth, int nHeight ) : Shape(nWidth, nHeight) {};

    double getArea() { return m_nWidth * m_nHeight; }
};
