If you turn over every programming book for beginner (also intermediate level), the first program you red is normally named as “myfirst” and the program content is about displaying (print out) a simple statement “Hello, World” on the console. Please don’t look down on this simple program code, it carries a lot of meaning to the programming language you are looking at. It demonstrates the program structure of the language itself, how you interact with the editor and also the programming syntax look like.
Neil Armstrong, the first man landed on the Moon had said that “One Small Step for Man, one giant leap for mankind”. Your “myfirst” program file, a big project for mankind. As such, please respect myfirst and hello, world.
