Implementing Binary Operators in C++ - Tutorial

Implementing Binary Operators in C++ - Tutorial  
ABSTRACT
 
In principle, implementing binary operators such as operator= and operator== is fairly easy for simple types, but is amazingly demanding for a class hierarchy of types. In this tutorial we will look into the complexities and will discuss solutions. The core of the problem stems from the fact, that objects in a class hierarchy have something in common, namely their base class part.  For this reason, it makes sense to consider mixed-type operations where objects of different types from the same class hierarchy are assigned to each other or compared to each other.  Does it make sense to allow mixed-type operations, and if so, how can they be implemented correctly?
