 There are 4 types of fundamental variables in ruby

-Global variables begin with $, 
-Uninitialized instance variables have the value nil 
-and produce warnings
+Global variables begin with `$`. Uninitialized instance variables have the value `nil` and produce warnings.

+An instance variable has a name that begins with `@` and its scope is limited to the object to which reference self.
