用計數機將你既icq number + 4294967296 2 g) P. F5 N- C
將計出黎個數 post 去 ICQ→加入→搜尋6 s3 n: O. c, T( v
就發現搜尋結果係........* C& C. ?, m, ~: C8 ]/ m
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面- H2 [( V* u+ F  A1 w
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)   M7 i" F& f( y7 V7 u
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)
e.g.
0 + 4294967295 = 4294967295 (max)
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
and so on....& i+ j5 l" o6 z; a7 ?9 V
