１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
2 q9 S& c$ E; x# [5 D4 }將計出黎個數 post 去 ICQ→加入→搜尋
& ^1 z) k8 n9 M- |' X就發現搜尋結果係........
6 |* o/ J; k% M1 h一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面+ ~/ L7 O9 e. G  p
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
+ y5 ^5 b: Q3 }+ i$ 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)4 u6 M: [. i& u) p9 V+ D) }7 H
e.g.
! Q! a. d3 B1 l0 + 4294967295 = 4294967295 (max)* i$ P9 m  ?$ e8 F5 W- I
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
