6,919 PointsWhere are the @ variables in this class?
I thought an object used @ instance variables. From the code in the video and teacher's notes the variables ought to be local and hence only accessible within a given method.
Does using an attr_accessor statement automatically create the @ variables for the class?

17,825 PointsYup that's the idea.
attr_accessor
is a shortcut for attr_reader
+ attr_writer
.
# What attr_reader gives you
def attribute
@attribute
end
# What attr_writer gives you
def attribute=(argument)
@attribute = argument
end
