What are attributes in Ruby?

In Ruby, attributes are variables that hold data related to an object. They define the state of an object.

How do I define attributes in a Ruby class?

You can define attributes using instance variables, typically prefixed with '@', and you can use 'attr_accessor' for getter and setter methods.

Can you give me an example of using attributes in a class?

Sure! Here's a simple example:

class Dog
  attr_accessor :name, :breed

  def initialize(name, breed)
    @name = name
    @breed = breed
  end
end

This defines a Dog class with name and breed attributes.

What is the difference between attr_reader, attr_writer, and attr_accessor?

attr_reader creates a getter method, attr_writer creates a setter method, and attr_accessor creates both.
