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

Ruby
1

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 }

Homework?

No… its for company-question … i have to understand this code asap…
also i am new to ruby…

Funny. A company dabbling with Morse code in the 21st century…
I may want to send them a CV…!

If you know neither Ruby or C++ then no one can help you. The job you
are
trying to get will have much harder problems than this interview
question.

i know C++ but don’t know the algorithm of morse-code
conversion…
finally i found the program in RUBY language… but i don’t understand
it… explaining this code steps-by-steps will be grateful …

plz help…

Hi,

Is this a joke? My advice: read a Ruby book to get familiar with the
Ruby language.

So you also do not know how to use Google?

“convert morse code to text in C++”

It takes a stream of . and - and sees what it might be:

$ ruby morse.rb
…-…-…-…
All Possible Decodings:
EAEAEAEE
EAEAEAI
EAEAEED
…

Of course you could run the program and find out for yourself.

i know C++ but don’t know the algorithm of morse-code
conversion…
