Question

这是Ruby的第一次教学的Pig_Latin。这是我的代码。起初，它运行并且它停留在2辅音但现在它不再运行了。

def translate(a)
    if a.split(' ').size > 1
        a.map {|x| pig(x)}.join(' ')
    else
        pig(a)
    end
end

def pig(word)
    vowels = %w(a o i e u)
    alphabet = ('a'..'z').to_a
    consonant = alphabet - vowels

    if vowels.include? word[0]
        word + 'ay'
    elsif consonant.include? word[0] && word[1]
        word[2..-1] + word[0..1] + 'ay'
   elsif consonant.include? word[0]
        word[1..-1] + word[0] + 'ay'
    else
        word
    end
end

我用rspec测试，这就是我得到的

帮帮我吧!!!感谢

问题解决了。那时我是个菜鸟。谢谢你们

Answer 1

pig_latin.rb:55: syntax error

错误回溯告诉你错误：语法错误。仔细检查您的代码。每个if语句都需要相应的end。与def相同。类也需要end，代码块也以do开头。

Answer 2

从它的外观来看，你还没有终止你的if。每条多行if/else都应该匹配end。

 if ...
     # happens if true
 else
     # happens if false
 end # <== don't forget this
