Before you plagiarized the comp.lang.c FAQ (your "C interview
questions"), did you read the following notice?

 comp.lang.c Frequently Asked Questions

 This collection of hypertext pages is Copyright 1995-2005 by Steve
 Summit. Content from the book "C Programming FAQs: Frequently Asked
 Questions" (Addison-Wesley, 1995, ISBN 0-201-84519-9) is made
 available here by permission of the author and the publisher as a
 service to the community. It is intended to complement the use of
 the published text and is protected by international copyright laws.

Especially this part:

 The on-line content may be accessed freely for personal use but may
 not be published or retransmitted without explicit permission.

I don't see any attribution or even mention of the original, so I'm
guessing you completely missed the part about "explicit permission".
