a code kata is an exercise in programming which helps hone your skills through practice and repetition. code kata is a term coined by Dave Thomas, co-author of the book The Pragmatic Programmer.

every few days, before lunch at work, me and my teammates are going though one of Gang of Four design pattern (just 15 minutes), later on, i'm coding it in c++ for practice.

code is compiling cleanly under g++ and clang++ with -Wall -pedantic. tested on MacOs 10.6, no animals were harmed; one cat was harassing me.

one pattern, one file, no hassle.
