Obfuscated C programs: Introduction

If you program long enough, eventually you will run into a programming art category called "obfuscated code" or “code golf”. You can find these especially at IOCCC. In this video I introduce the concept and the basic ideas behind such design. More information below (click "Show more").

I realize the category is "obfuscated code", not "small code", but often trying to compress your code into the smallest size will also effectively obfuscate its function. I also realize that some of the individual changes I did in the video did actually _not_ result in smaller program code size, but the opposite. But the end result is still the shortest I could manage, if you remove the "int", the "return", and the space after "include".
Actual obfuscation techniques include using small and meaningless variable names, using unusual syntax constructs, redefining reserved words, adding code that appears to do one thing but does something else (or nothing at all), creating a complex machinery (such as an interpreter) to do a different task, encryption, and so on.

I got to use the word "defenestrate"!
