Question Mark Operator
Ruby has a question mark (
?) operator that works like so
> ?a => "a" > ?\s => " " > ?? => "?" > ?a + ?b + ?c => "abc"
It essentially creates single character strings. At least in Ruby 1.9+ it
does. In versions of Ruby before 1.9, the
? operator could be used to get
the ascii character code of the operand character.
