１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
5 v( _# \3 ]: f將計出黎個數 post 去 ICQ→加入→搜尋
  i) K3 m! m2 A+ r3 K! m就發現搜尋結果係........2 S2 a8 d) B, }5 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3 Z+ F: M5 O4 {
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
" Y1 ]6 J% s) O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)9 W& e/ [2 w+ A5 o* _
e.g.
1 V2 p' Z$ S/ L& O! S9 a0 + 4294967295 = 4294967295 (max)
$ }$ C4 @' l, p( ?  m& \1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)- X. @  T. d4 M( T! _: g
and so on....
