20 ‘Hello, world’ programs to test how well you can
identify programming languages, both popular and arcane. ‘You’d be
a versatile coder indeed if you were fluent in every language in
the modern developer’s toolbox. Yet you don’t have to be a wizard
in every language to be able to tell which is which.We’ve assembled examples of the simplest program of all —
“Hello, world” — for 20 different programming languages. We’ve
often included some extra lines of code, such as function
definitions and comments, where it can help you distinguish one
language from others that have a similar syntax. Watch for telltale
clues.’
