puts #{a} doesn't do anything (except return nil), so I'm going to assume you
meant to say puts "#{a}". Since that does the same thing as puts a but is more
to type, I'd always use the latter. The #{} syntax is only useful when you
want to print out more than just the content of the variable. For example:
puts "The value of x is #{x}"
