ruby​​ excercise for name.lenth.t_s

Question

書中的練習說我應該單獨詢問姓名，然後獲取姓名的長度。我被困在第八行？這是我應該怎麼做的名字？

puts "What\'s your first name?" 
    first = gets.chomp 
    puts "What\'s your middle name?" 
    middle = gets.chomp 
    puts "What\'s your last name?" 
    last = gets.chomp 
    puts "So, your full name is #{first} #{middle} #{last}." 
    name = # {first} #{middle} #{last} 
    puts "Did you know that are + #{name.length.t_s} + characters " 
    puts "in your + name + " 

非常感謝您的幫助！

應（使用紅寶石串嵌入）：

name = "#{first} #{middle} #{last}"
