Hello

Im new to ruby and programming and I saw a guy do this on a tutorial
video:

"Hello".each_char do |x|
puts x
end

The result was that it printed one letter in the string at a time until
it had printed the whole word "Hello" in a vertical line. My problem is
that this wont work when I try it and I've done exactly like he did it.
The only thing I can think of is that maybe I have another version of
ruby than he has, but perhaps anyone of you knows the answer?

what version of ruby are you running? It works for me on 1.9.1 on
windows. Try this:

> "Hello".each_byte { |x| puts x.chr }

Thanks, the example you made works (alto I didnt fully understand it).

Im about 95% sure that I am running ruby 1.8.6 since I just used the
one-click installer that's on ruby-lang.org. Why dont they have a
one-click installer for the latest version of ruby? XD

I think the 1.8x version of Ruby's string implementation is in another
module: jcode. I believe you can run your original code, you just have
to require 'jcode'.

I don't know why they haven't packaged a more up-to-date one-click
installer. They do have the 1.9.1 version pre-built for windows. I'm
running it and it works great.
