C-puzzle-book-answers Answers with commentary/discussion for selected problems from The C Puzzle Book, 2nd ed. (Do not confuse this with --also a worthy tome, but completely different.) The number of programming books that have stayed in print, mostly unchanged, for 20 years, is pretty small. The C Puzzle Book is an excellent resource for anyone looking for help learning the arcane corners of C. I had intensive instruction in C programming in college, and used the language for several years professionally writing device drivers, but I was still surprised, working through the problems in this book, by how many intricacies there are to the language that I did not understand clearly.

Interestingly, many of these details are covered in the specification of the language--i.e., it's not like they are undefined behavior because the language has no formal specification other than its implementation (some widely used languages fall into the latter category, unfortunately for their heavy users--Ruby comes to mind). Rather, these details are specified, but poorly understood because they do not come up every day. Even with a small language it is not easy to keep all the rules in mind all the time. The C Puzzle Book includes answers for the exercises, but the explanations are sometimes terse or give you the why but not the how. In this repository, as an ongoing project, I'm trying to write down notes on the problems that I found more interesting or surprising, with my own more detailed commentary than the original book. For most of the problems that I thought were worth commentary, I've also saved you the trouble of typing in the code--I had to type it in and run it myself in order to understand it! Pull requests will be gratefully considered!

Like many screensavers based on the hit films, this one shows the famous Matrix code moving across your screen vertically, although it boasts a nice feature set you may not find in similar programs. Best of all, this screensaver is free and won't burden your PC with any sort of spyware. Rather than putting an EXE file on your desktop, The Matrix Screen Saver forces you to copy an SCR file into your Windows directory. You can specify the appearance of the title and scanning sequences, make the screensaver show the current time, and even choose the telephone number and username to display.
