Answer Source


if name.empty()? 

is interpreted as ternary 'if' operator inside regular if statement:

if (name.empty() ? do_somethig : do_something_else )

and double dot is missing is not found in your code

maybe you meant this:

if name.empty? # is equal to
if name.empty?()

Because question mark is a part of method name
