Hi! I'm trying to write a program that will print out a different
string each time it's run from a list of strings.
For example:
example = ['one', 'two', 'three']
# sort them somehow
# 'two' prints out as the output, for example
# run it again and a different string prints out
Make sense? I've tried srand & rand but can't do this with strings. Do
I need to forget the arrays and try something else? I've looked at the
Pickaxe book and Ruby Cookbook but can't find anything. Thanks!
try
example= %w[one two three cat dog cow table]
puts example[rand(example.size)]
Cheers,
Dave

Another example would be:
example= %w[one two three cat dog cow table].sort_by { rand }
example.each { |string|
puts string
}
that will print all in random order

We have not succeeded in answering all of our questions.
In fact, in some ways, we are more confused than ever.
But we feel we are confused on a higher level and about more important
things.

You can replace the last three lines with:
puts example

I apologize. I didn't read the current quiz.
Does that mean I have to check back with the current quiz when somebody
asks for help in here?

Ok time to clarify.
#sort_by{ rand } is fine, it is my head that is broken, so it is time for
me to apologize
#sort{ rand } of course is not, but I'll get new reading glasses soon.

No I do not think so, no need to apologize either 
Well James is the "boss" of the quiz, but the ML and the Quiz are two
distinct matters.
I personally chose to try to avoid to post any material too much related to
the Quiz and furthermore I point it out to others who might not be
interested in the Quiz.
Quizzes can be spoiled by posts of course, I redrew a quiz once because the
issue was discussed three days before its due date, actually I think it was
a good thing because after the discussion I did not think my Quiz was very
brilliant any more:). James was just great he had another quiz to come up
with immediately.
AFAIAC your reply has been very thoughtful, do not worry!
Cheers
Robert
P.S. Quiz Advocacy, checking the quiz is a good idea anyway :)))

Overlap happens. No big deal. It just means I chose well for the quiz topic and it will be helpful in the future.
