Rubic
I new to Ruby and I have lost touch with whatever little programming I
did know a few years back. Sorry if this is a lame question.
How does one nest arrays?
I want to check every element of the array and compare it against rest
of the elements of that array for repeat occurences. but for now I did
be happy if I can get to even print the 2 values, hence 'puts #i, #j' in
the code.
f = File.open("iplist.txt")
f1 = File.open("iplist.txt")
f.each { |i|
f1.each { |j|
puts "#{i}, #{j}"
}
}
With the above code I only get output of one successful iteration of
f.each and it stops and doesnt continue for the rest of the values of
f.each.
Surprisingly this works...
(0..5).each { |i|
(0..4).each { |j|
puts "#{i}, #{j}"
}
}

......etc
whats the difference between the codes thats causing this error? They
are both arrays aint it?
Thanks.
