If you wish to learn C, the classic text - the "Bible" - is "The C Programming Language", 2nd Edition, by Brian Kernighan and Dennis Ritchie. This hallowed text describes and explains ANSI C. K& R2 is renowned for its brevity, clarity, elegance and completeness; but these very factors can make it heavy going for the beginner. http://cm.bell-labs.com/cm/cs/cbook/
K N King's "C Programming: A Modern Approach" is another text frequently recommended on comp.lang.c. This book is a good, thorough introduction to C that is a lot easier to work with from a beginner's perspective. http://knking.com/books/c/
Another frequently recommended book on C is "C - How to Program", 2nd Edition, by H M Deitel and P J Deitel. Please note that I have not had a chance to read this book, and include the reference on the strength of the the recommendation of a number of regular posters to comp.lang.c. http://www.deitel.com/products_and_services/publications/chtp2.htm
