１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 % c5 f( v/ b4 o6 t% W$ e; U
將計出黎個數 post 去 ICQ→加入→搜尋) K7 }9 S- W' {- j' _* L
就發現搜尋結果係........
2 S* H4 _6 k# U4 H. I& `/ w; V一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面1 c% c9 V/ g, o. P0 @
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
: y, ]; H# ?/ g& b  u2 D! 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)& z0 ~$ c: P+ X( D  E5 O8 C* T
e.g.
* {8 e, Q& g, K9 C3 {* S: z4 k0 + 4294967295 = 4294967295 (max)3 c; ~- W1 u3 v1 g, \! x
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
( U$ u/ h; e: ]/ R  Jand so on....  H1 C$ L+ |# J$ ^. \' o
$ d3 z' k% N3 Y  m$ C+ ?0 v( m3 k- g
