Answer Posted / Nitesh Agrawal

Ruby classes have four types of instance variables: @variable (instance variables), @@variable (class variables), @variables (singleton class variables), and local variables. Instance variables are unique to each object, class variables are shared among all instances of a class, singleton class variables are unique to the class itself, and local variables exist only within their method or block.
