class Testdeck
    attr_accessor :cards

    def initialize
        @cards = []
        counter = 0
        ['H','C', 'S', 'D'].product['2','3','4','5','6','7','8','9','10','J','K','Q','A'].each do |arr|
            @cards << Card.new(arr[0], arr[1])
        end
    end
end

zen = Testdeck.new
puts zen.cards.pop

我花了最后一小时试图修复此错误.我得到的错误是:

wrong number of arugments (Argument Error)

我无法让这个工作.我得到的错误是:

114''numberstash':未定义方法'cards'代表nil:Nilclass(无方法错误).

这是一个二十一点游戏.我花了几个小时试图修复这段代码,包括制作一堆测试脚本来解决这个问题.但是,我没有运气.这适用于我的测试脚本,但它不适用于当前脚本:

class Card
  attr_accessor :suit, :value

  def initialize(suit, value)
    @suit = suit
    @value = value
  end

  def to_s
    "#{value} of #{suit}"
  end
end

class Deck
  attr_accessor :cards

  def initialize(number_of_decks)
    @cards = []
    num = number_of_decks
    counter = 0
    while counter < num
      ['H','C', 'S', 'D'].product(['2','3','4','5','6','7','8','9','10','J','K','Q','A']).each do |arr|
        @cards << Card.new(arr[0], arr[1])
      end
      counter += 1
    end
  end
end

class Player
  attr_accessor :cards, :testvalue

  def initialize
    @cards = []
  end
end

class Dealer
  attr_accessor :cards

  @cards = []
end …
