I am sorry debleena, but I still couldn’t understand what you wanted to say, please explain it to me. What my intention was I already mentioned in my previous mail.I am still confuse what do you want to say in this statement

Quote:

This total depend on system how r u implementing

What total are you talking about this? And what is depends on system? Do you want to say that recursion depends on system?

Quote:

But you cannt mention as " originally written zeesan in asadullah.ansari article."

Can you please explain when did I mention this thing? What should be written or not written with this article, I have already left that decision to the moderator. And you may also understand that I am not a moderator to change others post.

Quote:

same explanation by this book also. Can you blame to those writers also who mention this book as in his articles.

For your kind information this is not a book, this is in fact an article published in “Journal of Computing Science in Colleges” in October 2006. Did you actually get a chance to see this article (or so called book) yourself? If you are a member of ACM then you can access it form ACM Digital Library. And for your kind information I have actually read that article. This 7 page articles has nothing to do with recursion type it only deals with “Recursively-Generated Geometric Designs” and discussed "Nested Triangles, Nested Polygons and Fractals" I can’t post the whole article here, but for your reference let me copy its abstract here

Quote:

Teaching about recursion usually involves programs arriving at answers and displaying the results (for example: quicksort, summing elements in a linked list, evaluation of an expression tree). This paper discusses problems that naturally display results at each recursive step. Examples of these programs include those that visually display fractals and other geometric shapes recursively.

You can read this abstract yourself from here

Even more interesting is that this reference is also copied from this article.

http://www.codeproject.com/KB/cpp/Re...mr_CPP_01.aspx
This reference was mentions properly in the above article by explaining what reader should expect in it, not adding the reference just for the sake of something in the reference section. Here is the excerpt from the above article that refers to this.

Quote:

Usually, recursion is a little bit difficult to understand for most students. Researchers usually come up with different strategies to teach recursion easily for students, such as teach recursion before teaching arrays [4], delegations [2], or recursively generated geometric designs [3].

Here number 3 is the reference of

**“Teaching recursion using recursively generated geometric design, Aaron Gordon”**
If you have time then I recommend you to take a look at its second part before someone write an article based on it without even giving the credit where it is due, from here

Can you please explain a little bit what you want to ask or say to me?
