乱码程序，乱的很有规律

This page combines two things I like: "Hello, World!" programs and obfuscated C programs. The following programs should all compile with GCC and the Borland command line compiler for Windows (bcc32).

hello6.cpp

Cheating a bit here. This only works with a cpp compiler (tried it with g++).
