how to use Const

[Pat Nevin]

Hi have just wrote a simple C++ project, Which includes a baseclass and two subclasses, Im new to C++ so finding it a bit confusing using subclassing and polymorphism compared to how simple it is in Java.

Basically I'd like to know how to declare and create methods which are both const and virtual in the base class and how to avoid errors when trying to use pure polymorphism in the childclasses, i.e. do i also have to declare the methods in the child classes virtual and const if i wish to redefine there functionality.

Also how to declare and assign a value to a const member variable....

Many thanks
