Displaying a Menu

3:57 with Jason Seifer

Our users will need a way to interact with our program. In this video, we begin to offer that functionality by displaying a simple menu and waiting for input.

Code Samples

def run
  loop do
    puts "Address Book"
    puts "e: Exit"
    print 'Enter your choice: '
    input = gets.chomp
    case input
    when 'e'
      break
    end
  end
end

We call this by saying:

address_book.run
