Storing user input into hash RUBY -

-

im trying store of user's input hash , loop through hash , display results. input: first name, last name, age, city visited(user input multiple cities until input "exit".

here's got far..and looks except being able separate cities multiple values when multiple cities entered. 

result = "" print "enter first name " first = gets.chomp print "enter last name " last = gets.chomp print "enter age " age = gets.chomp  while true print "enter city" city = gets.chomp if city == "exit"   break end result = result + " " + city end  user_data = { first: first, last: last, age: age, city: result}  puts "#{user_data}"

it's better use array purpose, this:

cities = []  loop   print "enter city: "   city = gets.chomp   if city == "done"     break   end   cities << city end  user_data = { first: first, last: last, age: age, city: cities}

and after can make string representation joining elements of array, example 

cities.join(' ')
