１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 4 `% j6 w% _7 C& j- e, x1 b6 y0 O
將計出黎個數 post 去 ICQ→加入→搜尋. }3 V) Y1 O1 t
就發現搜尋結果係........8 I5 G3 G2 ?: v# A
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面
+ r5 j. ?4 e5 J2 u9 f' h  IMaximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) + w  c( w, h0 S+ @+ d6 y. H( ^/ ~
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 [$ U% f9 v% W5 X) X
e.g.5 c* g8 R* c/ u" P1 v
0 + 4294967295 = 4294967295 (max)  d( X6 M2 R' c! ^
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)7 B1 m- j: F4 K+ B. }
and so on....
