１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 5 K6 l/ r; l3 N! ^: A/ P1 z7 W
將計出黎個數 post 去 ICQ→加入→搜尋7 a9 ^9 o% N; A2 v  j1 x( P# P5 ?  ~
就發現搜尋結果係........

- M8 l! R7 m" z5 J/ c, m好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面. C$ ?" x6 Z9 J" D% x6 D& Z
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
0 Z$ U( J& I5 K8 Q7 T1 S: V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)# t; O9 Z, E# y/ ]8 Q2 ~; @+ q
e.g.2 H. A4 ?* B& b3 x
0 + 4294967295 = 4294967295 (max)
, ]1 [9 P* Q& ~% ~# ^" U1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
