Deck of cards , using class Card and Deck

Deck of cards

class Card
  attr_accessor :rank, :suit

  def initialize(rank, suit)
    self.rank = rank
    self.suit = suit
  end

  def output_card
    return "Card: #{self.rank} of #{self.suit}"
  end
end

class Deck
    
    def initialize()
        ranks = %w{ A 2 3 4 5 6 7 8 9 10 J Q K}
        suits = %w{Spades Hearts Diamonds Clubs}
        @cards = []
        suits.each do |suit|
            ranks.each do |rank|
                @cards << Card.new(rank,suit)
            end    
        end
    end
    
    def shuffle
        @cards.shuffle!
    end
    
    def deal
        card = @cards.shift
        puts "Dealing - " + card.output_card
    end
    
    
    def count
        puts @cards.size
    end
    
    def output_deck
        result = ''
        @cards.each do |card|
            result += card.output_card + "\n"
        end
        puts result
    end
end

deck = Deck.new
#deck.output_deck
deck.shuffle
deck.deal
deck.count

deck.deal
deck.count

For deal & count , instead of the puts statement, try to return the value and the caller will call it. Same for output deck
