我是菜鸟刚入门
跟着这本书敲的第一段代码就运行不出结果
class Song
def initialize(name,artist,duration)
@name=name
@artist=artist
@duration=duration
end
def to_s
"Song:#@name--#@artist([email=#@duration]#@duration[/email])"
end
end
song=Song.new("My Way","Sinatrs",225)
song.to_s
尝试着在to_s方法中加了print结果打印出来了
class Song
def initialize(name,artist,duration)
@name=name
@artist=artist
@duration=duration
end
def to_s
print "Song:#@name--#@artist([email=#@duration]#@duration[/email])"
end
end
song=Song.new("My Way","Sinatrs",225)
song.to_s
-------------------------
是不是因为RUBY更新得太快了呢?
想找书的源码看看呢 ,发现官网(
http://www.pragmaticprogrammer.com/titles/ruby)的源码下载下不了 报"HTTP 错误 403 - 禁止访问"
哎!哪位大侠知道哪里有下载啊? 或者可以给我传一下的? 先谢谢啦!
