def check_age
  print "Please enter your age: "
  age = gets.chomp.to_i
  eligible = 18..30

  if age == 0
    print "Please enter a two digits number in � 18..30 �."
    check_age
  elsif eligible === age
    print "Have a great holiday!"
  else age < 18
    print "Sorry, too young."
  end
end

check_age


the "gets.chomp.to_i" returns 0 when only alphabetic chars. ie :

"toto" => 0

or :

"blahblah27yyyiyiyiyui" => 0
