楼主做什么滴?
怎么还经常能看到这种代码?

对啊对啊~~~~上次好象看到有这个比赛的
比看谁写的代码别人读不出来！绝对经典
不过蛮无聊的……实际的都用不上

今天再看了一下，其实可以这样理解，将它拷贝下来后命名为1.c用VC打开即可编译
看下面：
#include <stdio.h>

char* AAA = "%s %d %d\n";

char*BBB = "@n'+,#'/*{}w+/w#cdnr/+,{}r/*de}+,/*{*+,/w{%+,/w#q#n+,/#{l+,/n{n+,/+#n+,/#\
;#q#n+,/+k#;*+,/'r :'d*'3,}{w+K w'K:'+}e#';dq#'l \
q#'+d'K#!/+k#;q#'r}eKK#}w'r}eKK{nl]'/#;#q#n'){)#}w'){){nl]'/+#n';d}rw' i;# \
){nl]!/n{n#'; r{#w'r nc{nl]'/#{l,+'K {rw' iK{;[{nl]'/w#q#n'wk nw' \
iwk{KK{nl]!/w{%'l##w#' i; :{nl]'/*{q#'ld;r'}{nlwb!/*de}'c \
;;{nl'-{}rw]'/+,}##'*}#nc,',#nw]'/+kd'+e}+;#'rdq#w! nr'/ ') }+}{rl#'{n' ')# \
}'+}##(!!/";

char* CCC ="!ek;dc i@bK'(q)-[w]*%n+r3#l,{}:\nuwloca-O;m .vpbks,fxntdCeghiry";

main(t,_,a)
char *a;
{
return!0<t?t<3?main(-79,-13,a+main(-87,1-_,main(-86,0,a+1)+a)):1,t<_?main(t+1,_,a):3,main(-94,-27+t,a)&&t==2?_<13?main(2,_+1,AAA):9:16:t<0?t<-72?main(_,t,BBB):t<-50?_==*a?putchar(31[a]):main(-65,_,a+1):main((*a=='/')+t,_,a+1):0<t?main(2,2,"%s"):*a=='/'||main(0,main(-61,*a,CCC),a+1);
}

怎么加入些语句，使这个程序能够分页输出？

The Strings
There are 2 major strings in the program. The first one is encrypted with a substitution cypher - the second string is the key of the cypher.
The key string is:
"!ek;dc i@bK'(q)-[w]*%n+r3#l,{}:\nuwloca-O;m .vpbks,fxntdCeghiry"

For an encrypted character at index X in the key, the decrypted value is at index X+31 in the key. So '@' at index 8, decrypts to the character at index 39, 'O'. Notice that '!' (index 0) translates to '\n' (index 31).

The first string in the program - the one encrypted with they cypher is:

"@n'+,#'/*{}w+/w#cdnr/+,{}r/*de}+,/*{*+,/w{%+,/w#q#n+,/#{l+,/n{n+,/+#n+,/#\
;#q#n+,/+k#;*+,/'r :'d*'3,}{w+K w'K:'+}e#';dq#'l \
q#'+d'K#!/+k#;q#'r}eKK#}w'r}eKK{nl]'/#;#q#n'){)#}w'){){nl]'/+#n';d}rw' i;# \
){nl]!/n{n#'; r{#w'r nc{nl]'/#{l,+'K {rw' iK{;[{nl]'/w#q#n'wk nw' \
iwk{KK{nl]!/w{%'l##w#' i; :{nl]'/*{q#'ld;r'}{nlwb!/*de}'c \
;;{nl'-{}rw]'/+,}##'*}#nc,',#nw]'/+kd'+e}+;#'rdq#w! nr'/ ') }+}{rl#'{n' ')# \
}'+}##(!!/"

When it is decrypted it looks like this:

"On the /first/second/third/fourth/fifth/sixth/seventh/eigth/ninth/tenth/eleventh/twelfth/ day of Christmas my true love gave to me
/twelve drummers drumming, /eleven pipers piping, /ten lords a-leaping,
/nine ladies dancing, /eight maids a-milking, /seven swans a-swimming,
/six geese a-laying, /five gold rings;
/four calling birds, /three french hens, /two turtle doves
and /a partridge in a pear tree.

/"

The slashes are not in the cypher key; they are used to divide the encrypted string into a sequence of substrings. One of the functions of the program decrypts and prints the Nth substring in the sequence.

For more on substitution cyphers, you can check out my solver, which I wrote as an example of using STL.

--------------------------------------------------------------------------------

Basic Outline of How it Works
You probably have a good idea of how it works right now:
main(){
for(day = 1; day <= 12; day++) {
decrypt_and_print_substring(0);
decrypt_and_print_substring(day);
decrypt_and_print_substring(13);
for(gift = day; gift >= 1; gift--)
decrypt_and_print_substring(26 - gift);
}
}

Now, the program does not have loops, so both for-loops are done via recursion. It may appear that there are no sequential pieces to the actual code, but there are. For sequential operations the author either uses the comma operator or does multiple function calls in a single line (e.g. main(main(main()) - the inner most call must be done first).

这么断的程序竟然可以输出这么多东西？奇怪。。

那些用VC编译的兄弟们，你们在CMD 模式下用 cl xx.c 编译就可以了。

当然是他们手动写的，要是用正则表达式他们就不能算是高手了。
如果写好后，用正则表达式替换，那我也能写出来一两段。

混乱C程序，是有些牛人们，为了证明没有良好的编程风格也能写出好的程序而作的代码。他们的目的就是，让别人看不懂他的代码，而且程序能完成功能。
