okay, so in the book im reading it wanted me to do 2 things



1) wanted me to make a method for sorting a list of words

this is what i got now

def arange
arr = []
puts arr.sort.join(', ')
word = gets.chomp
while word != ""
arr << word
word = gets.chomp
end
end

arange

why isnt it working?




2) It wants me to make and "old school roman numerals" thing

so if i put a number it, it would return it in roman numerals, but NOT
subtraction
so like 4 would be IIII , not IV


IM CONFUSED WITH THAT!!! any body can give me a little hint on how to
start?
thx

Daniel,

I am not sure if your comment: "that was helpful" was meant to be sarcastic
or if you really found the link helpful.
However, if you if you still needs help, see below:

I am no Ruby expert but I re-arranged your code and it works:

def arange
arr = []
word = gets.chomp
while word != ""
arr << word
word = gets.chomp
end

puts arr.sort.join(', ')

end
arange

ruby mypgm.rb

orange
banana
Apple
Banana
Cherries
mango

Apple, Banana, Cherries, banana, mango, orange

For your second question I also find it confusing. But you can find many
examples on the web, *google*, about playing with roman numerals.
