[Daniel Kindler]

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

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

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