I encourage you all to check out what i am currently reading, http://www.cs.cf.ac.uk/Dave/C/CE.html

This tutorial is the best C resource i have ever seen readily available legally on the net. Its as if K&R wrote it themselves

This guide will teach you virtually everything you will ever need to know about C, everything. Have fun, should take you o.. a few minutes to read the whole thing, as for me, im printing it out :P
