Instance variable creation

What is the purpose/meaning of the second line in the code below? @age = 0 I don't understand why there is an instance variable @name declared inside the class but outside the method. What does this create? what is its scope and use? class Animal @age = 0 def initialize(name, age) @name = name @age = age end end

I think it sets an atribute age that is equal to 0 for every member of the class Animal and by adding @age=age you're saying that age can be different from 0 if specified (I quite forgot Ruby oop but this is what I think it is...)

This is an excellent question. Give me a few minutes to reply with a response that will hopefully be short and clear.
