I believe this is just showing you what data is stored in which slot in the array. a[0] contains "ant", etc. On 3/13/06, Bobby <damienov@gmail.com> wrote:> > Im just learning trough the "geting started with ruby" > i''m only on page Ruby.new and im stuck > here''s the thing, I''m using FreeRIDE to duplicate the examples > > a = %w{ ant bee cat dog elk } > a[0] ?

You don''t need to actually type in the "?". In the code, that convention is used to show you the output/value of the expression on the left.

This might explain it better than me: http://www.rubycentral.com/book/preface.html Go there and read the section on "Notation Conventions".

That character and anything after it is not part of the actual sample code.

a[0] ? "ant" a[3] ? "dog" is equivalent to "reading" a[0] has a value of "ant" a[3] has a value of "dog" it''s strictly there for visualization purposes and has not meaning outside that context, ie, it''s not code.
