１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
$ {# ~7 p% o' c" Y+ ?9 |6 x+ x" K將計出黎個數 post 去 ICQ→加入→搜尋# e- v0 W$ W3 w( d$ U
就發現搜尋結果係........( @# N# \, N2 J3 w: C$ p
一個你都識既人!!!!

有無人知點解?

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面8 ]% r# g* x, x- A8 O
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
" I) A6 O( |4 ]4 ]: W6 a個 value 過左呢個 range 就會 overflow , 佢只會理最後個32bits 數 (即係好似返返轉頭 , 循環咁)8 S$ ?3 C8 O+ Q( L6 y1 c; G
e.g.
$ W3 z$ ^7 U- D% a" S3 `0 L0 + 4294967295 = 4294967295 (max)
# a# V& ~; S+ B& J1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
% K0 S8 K7 R& ]+ E* d2 o7 Vand so on....
