Programmer, smart, genius, abnormal and neurotic… If you know something about programmers, probably you often above words to describe a programmer. If you know a little on programming, you should unmitigatedly  understand all above adjective after you read below 6 “Hello world” programs written in C.

If you can read and understand all of them or even you can write something such as them, congratulation, you are one of the “Abnormal” & “Neurotic” of programmers.
