私は基本的にZed ShawのRubyコースの紹介を途中でやっています。しかし、私はこの演習では、彼が私にコードの一部を与え、それを修正するように私に頼んで、ロードブロッキングで立ち往生しています。エラーの多くは文法的なものでしたが、コーディングできないものもあります。Zed Shawのルビーのエクササイズにつきました
次のように私が得るエラーは以下のとおりです。
ex26.rb:76:構文エラー、予期しない ')'、期待 '='
ex26.rb:99:構文エラー、予期しないが$エンド、
')' コードを期待:
# This function will break up words for
def break_words(stuff)
words = stuff.split(' ')

# Sorts the words.
def sort_words(words)
return sorted(words)
end
# Prints the first word after popping it off.
def puts_first_word(words)
word = words.poop(0)
puts word
end
# Prints the last word after popping it off.
def puts_last_word(words)
word = words.pop(-1)
puts word
