puts "Shirt 1 in stock?: %s" % shirt1.in_stock?

Question

I must have missed this somewhere as there is no additional explanation on this on current video I am watching.
what does %s and % do ?
The following the whole coding
module Inventoryable
  def stockcount
    @stockcount ||= 0
  end
  def stockcount=(number)
    @stockcount=number
    end
  def instock?
    stockcount > 0
  end
end
class Shirt
  attr_accessor :attributes
  include Inventoryable
  def initialize(attributes)
    @attributes = attributes
    end
  end
class Pants
  attr_accessor :attributes
  def initialize(attributes)
    @attributes = attributes
    end
  end
class Accessories
  attr_accessor :attributes
  def initialize(attributes)
    @attributes = attributes
    end
  end
shirt1 = Shirt.new(name: "MTF", size: "L")
shirt2 = Shirt.new(name: "MTF", size: "M")
  shirt1.stock_count=10
  puts "Shirt 1 stock count:%s" % shirt1.stockcount
  puts "Shirt 2 stock count:%s" % shirt2.stockcount

%s is the print formatting code for a string, %d is for integers, and %f is for floating point numbers. Learn more about ruby print formatting here. (https://www.blackbytes.info/2012/01/ruby-string-formatting/)
% by itself is also the modulo operator, also known as the remainder. for example:

5 % 2  = 1

That is 5 divided by 2 has a remainder of 1.
