Converting an array of numbers to characters ruby [closed]

by

You create instance of Encrypted method, but you set @code = 2, @string = "Hello" and @encrypted = []. So if you call @encrypted[0], ruby return nil.

So you can modify your class like this:

class Encrypt
  def initialize(code, string)
    @code, @string, @encrypted = code, string, []
  end

  def to_byte
    @string.each_byte { |c| @encrypted << c + @code }
  end

  def to_chr
    to_byte if @encrypted.empty?

    @encrypted.map(&:chr)
  end
end

goop = Encrypt.new(2, "hello")
p goop.to_chr
# => ["j", "g", "n", "n", "q"]

I hope this helps
