Why Hello World?
Has anyone ever wondered why the default blog title is Hello World, why the output of your first program is Hello World and why every programming book always starts with the example - Let’s write Hello World?
There has got to be this one person who decided that lets begin with Hello World and then the entire world followed his or her example. I obviously googled to see if there were any clues to the identity of this person. The first link i got was, of course, a Wikipedia entry: “Hello World Program“. Wikipedia says “The first known instance of the usage of the words “hello” and “world” together in computer literature occurred earlier, in Kernighan’s 1972 Tutorial Introduction to the Language”. I think it could be safe to say that Kernighan is the father of “hello world” or “Hello World” and its other variations.
I am still surprised to see, that with all the IM Shorthand in use today, the phrase has not reduced to just “Howdy”, “HW” or “Hi”. Strange right? How about just printing “This is my first program in this programming language” or “testing” or “it works!”
Strange as it is, i eventually did end up writing my first blog about “Hello World”!
