6 perverted C-language Hello World programs

6 perverted C-language Hello World programs

The following six program fragments mainly accomplish these things:

1. Output Hello, world
2. Confusing C-language source code

All of the following programs can be compiled under GCC, only the last one needs to use C + + compiler g++ to pass the program.
