Answer / suman
is a class that provide certain functionality that other
class can inherit, but it is not meant to be a standalone
class.
Kind of an interface where soem members are predefined.
Pyhton and Ruby supports mixin. .Net does not.Can simulate
using Castle.DynamicProxy

Answer / sonali
A class that provides some but not all of the
implementation for a virtual base class is often called
mixin. Derivation done just for the purpose of redefining
the virtual functions in the base classes is often called
mixin inheritance. Mixin classes typically don't share
common bases..

Answer / reejusri
Mixin is a class that does not implement any method but are
in fact has only pure virtual methods. The implementor
decides the logic for these methods.
The term mixin were originally explored in the Lisp
language In C++, the term has been used to describe classes
in a particular (multiple) inheritance arrangement:
As superclasses of a single class that themselves have a
common virtual base
class .
We would like to specify an extension without pre-
determining what exactly it can extend. This is equivalent
to specifying a subclass while leaving its superclass as a
parameter to be determined later. The benefit is that a
single class can be used to express an incremental
extension, valid for a variety of classes.

Hi All, I am new to programming and want to know how can i write a code to take input of 2 numbers from user and swap it without using a temp variable?
to find out the minimum of two integer number of two different classes using friend function
suppose A is a base class and B is the derved class. Both have a method foo which is defined as a virtual method in the base class. You have a pointer of classs B and you typecast it to A. Now when you call pointer->foo, which method gets called? The next part of the question is, how does the compiler know which method to call?

i had specified the access specifier for abstarct class member like (pure virtual function) as private.But it can be accessed by the derived class.How the private member of one class is accessed by other class.if any body face this problem and found the solution plz reply to me.
