Hi there everybody!! I just wanted to say "Thank You!!!!" to everyone who replied to my question; all the answers were very useful indeed, and the URLs were quite excellent. You all really amaze me... I was extremely pleased!! Thank you sooo very much!!! :) :) If it's helpful to anybody else, here are the URLs that were so kindly given to me (they're excellent) http://elvis.rowan.edu/~berman/Book/index.html http://www.corplink.com.au/~renato1 I looked on mcp.com for "Sams' Teach Yourself Advanced C in 21 Days" but they didn't have it as an online book... It sounds good though.. Also, if anybody else is by chance going to take the AP Computer exam someday, there's a somewhat official page on it at: http://www.collegeboard.org/ap/computer-science/html/indx001.html But it doesn't even compare to the other wonderful pages that were posted... Once again, Thank You **very** much!!!!! I really appreciate it... You guys rule :) -Brett
