Subject: Conversion of Ruby-code to c/c++ code :: URGENT Plz help

Hi.. I urgent require to convert the following ruby-code to c/c++ code.
If some-one have both the knowledge ..plz help me..  At least give me
some algorithm to it..  IT's ABOUT THE MORSE-CODE CONVERSION TO STRINGS
IN ALPHABETICAL ORDER

----------------------------------------------------------------------

#!/usr/bin/env ruby -wKU
require "set"
MORSE_LETTERS = %w[.- -... -.-. -.. . ..-. --. .... .. .--- -.- .-..
--
  -. --- .--. --.- .-. ... - ..- ...- .-- -..- -.-- --..]
ENCODINGS = Hash[*MORSE_LETTERS.zip(('A'..'Z').to_a).flatten]

def morse_decodings(word)
  # iterate through matching prefixes
  ENCODINGS.select { |p,l| p == word[0,p.size] }.map do |
prefix,letter|

    # gather decoded suffixes for the current prefix
    suffixes = morse_decodings( word[prefix.size,word.size] )

    # append decoded suffixes to decoded letter
    suffixes.empty? ? letter : suffixes.map { |s| letter + s }

  end.flatten
end

decodings = morse_decodings(readline.chomp).sort

puts "All Possible Decodings:"
decodings.each { |e| puts e }
