General:
========
A class is NOT an object!

Class Definition:
=================
A class is the declaration of a specific data structure and any 
methods 
that operate on that data.  For example, the following is a class...

CMyClass
{
  public:
    void setValue(int iValue) { m_iValue = iValue; }
    int getValue() const { return m_iValue; }

  protected;
    int m_iValue;
};


Object Definition:
==================
An object is an instance of a class.

CMyClass firstInst, secondInst;

Both firstInst and secondInst are objects - they are instances of the 
class CMyClass.
