Should the beginner's program read "Hello, World"? [duplicate]
Solution 1:
Whilst according to my memory inserting the comma is technically correct, it is now rarely seen in everyday communications. I favour Hello World, therefore.
Solution 2:
Conventional orthography demands:
Hello, world!
but, given the context, it doesn't really matter what you type. In my experience, the following is common:
Hello world
Since a "Hello world" program terminates immediately after printing its message, I personally prefer:
Goodbye, world.
