Query: Absolute Beginner's Guide to C Programming 2nd Edition

Just as it says: A beginners guide. Some stuff a pro may have forgotten and need to refresh with also. But takes you by the hand. Examples, problem solving and gets you up and going. I've programmed for years, but it was refreshing to find some new tricks for the old dogs in this book. Put it on your shelf and you'll use it for reference from time to time. Just keep in mind, its a beginner book and one of the easiest learning books I have seen in a while. If you are advanced in C, then you may not need it, but I bought it as a reference and refresher course.
