输出数字 2014 ，但是源代码中不允许有任何数字

当然如果你不懂任何编程语言甚至英语都不行就可以无视这个了

开始！

RUBY 代码复制

p Time.new.year

p Time.new.year

太简单 ;)

RUBY 代码复制

Happy = Time
Happy.new.year

Happy = Time


Happy.new.year

这个不错，但是不够热情. 这样来:

RUBY 代码复制

Happy = Time
class Time; alias year! year; end
 
Happy.new.year!

Happy = Time


class Time; alias year! year; end


 


Happy.new.year!

哎哟不错哦~不过还有更厉害的:

RUBY 代码复制

class Have; def self.a; A.new; end; end
class A; def happy; Time; end; end
class Time; alias year! year; end
 
Have.a.happy.new.year!

class Have; def self.a; A.new; end; end


class A; def happy; Time; end; end


class Time; alias year! year; end


 


Have.a.happy.new.year!

这个好啊！不过语法不怎么对 我平常说话可不用打点：

RUBY 代码复制

def noop x = nil; end
alias a noop
alias happy noop
alias new noop
alias year! noop
def Have x
    p Time.new.year
end
 
Have a happy new year!

def noop x = nil; end


alias a noop


alias happy noop


alias new noop


alias year! noop


def Have x


    p Time.new.year


end


 


Have a happy new year!

哈哈，停不下来了：

RUBY 代码复制

def noop x = nil; end
eval %w[we wish you a merry christmas! christmas and a happy new].map{|x|"alias #{x} noop"}*"\n"
def year!; p Time.new.year; end
 
we wish you a merry christmas! we wish you a merry christmas!
we wish you a merry christmas and a happy new year!

def noop x = nil; end


eval %w[we wish you a merry christmas! christmas and a happy new].map{|x|"alias #{x} noop"}*"\n"


def year!; p Time.new.year; end


 


we wish you a merry christmas! we wish you a merry christmas!


we wish you a merry christmas and a happy new year!

祝大家新年快乐！

1. p sprintf("%#x","CABE".hex-"AAAA".hex)

复制代码

1. p "HappyNewYear~~\^>^/~~".sum

复制代码

方法还是很多的。

无脑之人

1. print true.object_id,false.object_id,false.object_id.object_id,nil.object_id
   
2. print nil.object_id*true.object_id.object_id,true.object_id*false.object_id.object_id.object_id.object_id
   
3. print( (false.object_id.object_id.object_id.object_id.object_id.object_id*true.object_id).object_id.object_id.object_id.object_id*true.object_id)

RUBY 代码复制

File.open("newyear.txt", "r") { |f| $number = f.read.to_i }
puts $number

File.open("newyear.txt", "r") { |f| $number = f.read.to_i }


puts $number

然后newyear.txt里是“2014”……

1. irb(main):002:0> %x(date /t)
   
2. => "2014-01-26 星期日 \n"

复制代码

于是

RUBY 代码复制

puts %x(date /t)[0, 4]

puts %x(date /t)[0, 4]

EDIT：上面那个代码里有数字……
EDIT2：第二个代码没有数字……

---

新研究了一种：

RUBY 代码复制

$r = 0
"Happy new year!   ,     Yay!".each_byte { |b| $r += b }
puts $r

$r = 0


"Happy new year!   ,     Yay!".each_byte { |b| $r += b }


puts $r

---

RUBY 代码复制

puts "BBC".to_i("\r".ord)

puts "BBC".to_i("\r".ord)

↑新加一只.w. @余烬之中
第二种重新修改了一下：

RUBY 代码复制

puts %x(date /t)[/\d\d\d\d/]

puts %x(date /t)[/\d\d\d\d/]

英顺的马甲

print "MjAxNA==".unpack('m').first

yagami

  a = "比♂利"=="王"
  b = a.to_s.size - (!a).to_s.size
  p (b<<b).to_s + (b>>b).to_s + b.to_s + (b<<b<<b).to_s

哈哈，Ruby-China果然还有6R的人……

不是马甲

对了 刚看到一位仁兄这样来：
'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ...

我没认真看给出来的= =还有一种类似输入 a b c d  每个字母分别对应相应X的个数

对了 刚看到一位仁兄这样来：

RUBY 代码复制

'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'.length

'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'.length

汗一个

然后除了ruby,其他的语言也有很多奇葩
比如最简短的源代码（长度为0！）用的是Python3.4.0b2（特别强调是3.4.0b2）
打开Python3.4.0b2就会自带提示

PYTHON 代码复制

% python3.4  
Python 3.4.0b2 (v3.4.0b2:ba32913eb13e, Jan  5 2014, 11:02:52) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>

% python3.4  


Python 3.4.0b2 (v3.4.0b2:ba32913eb13e, Jan  5 2014, 11:02:52)

有没有看到那个2014？

在C语言中 源代码写

C 代码复制

;#

;#

编译会出错 然后提示

RUBY 代码复制

testvc.cpp(1) : error C2014: preprocessor command must start as first nonwhite space

testvc.cpp(1) : error C2014: preprocessor command must start as first nonwhite space

呵呵

另外一个用Go语言的也是一样的思路

GO 代码复制

RUBY 代码复制

can't load package: package : 
prog.go:1:1: illegal character U+2014 '—'

can't load package: package : 


prog.go:1:1: illegal character U+2014 '—'
