１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 7 [# j& t  {' S) \" h) S
將計出黎個數 post 去 ICQ→加入→搜尋( L6 ]2 q8 V; p( q7 q5 V; n
就發現搜尋結果係........! z$ z" [  |! r
一個你都識既人!!!!

) J% F8 N$ p$ `7 g  w$ o! X好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面# b. E$ x$ t& s) Y9 e: U( F
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
$ U* e4 D, N8 V: \; D4 W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)2 s9 a/ c" K1 |- X4 F
e.g.
* g9 Y; V2 v2 ^# @' `0 + 4294967295 = 4294967295 (max)
9 L; t5 S+ C* ^+ H1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
