１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 ) |9 E0 X4 m3 E9 k0 X; X9 J
將計出黎個數 post 去 ICQ→加入→搜尋" q, l, C8 _  g& P6 K7 x
就發現搜尋結果係........
! Y8 P8 i$ P, |1 i9 |5 ^4 \7 p一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面" Z0 H7 x/ E& ^% y7 @2 D1 [5 F- }$ z
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 2 C6 r$ _, |2 E$ _# N" ^  Z
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)$ F2 P  O+ G4 N% Y2 X( _. }) ^/ D
e.g.
. g$ q: H* ]) `, v% c# i6 v0 Z0 + 4294967295 = 4294967295 (max)5 m( h+ x6 u& U3 C, ?# Z$ L/ q
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
