Hi Everyone :)

While going through some C++ articles. I came across the term "Node Class". I tried to google about same. But unfortunately didn't get complete information and also it was not clear.

If somebody has good understanding of Node class....How to implement it..where exactly it is useful etc etc. Please share your knowledge with EXAMPLE.

Thanks in advance :)

Happy Learning :)

In object oriented programming (OOP) , you can build a tree of classes.
For example might be some class A, which is inherited from the class B ,class B which is inherited from the class C.

Please see following image:
http://www.codeproject.com/KB/cpp/386982/standard_composite.GIF

The hierarchy of classes including one parent class and several child nodes.

1) Worker is Node
2) Manager is Node

Please read about the inheritance in C++ or C# or Java

Solution 2

A node class is simply a class representing a node in a data structure. Data structures like lists, trees, maps, etc. consist of so-called nodes. And a representation of such a node in form of a C++ class is called a node class. As simple as that.

If you don't understand what is meant my the term "node", go ahead and read about data structures. That will probably clarify things for you.
