１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 . D3 [3 Z+ Y1 x3 n9 e) F. S
將計出黎個數 post 去 ICQ→加入→搜尋
. f9 `, z( Y! \9 E2 n就發現搜尋結果係........
) Q2 t' \- d: S& {+ s# F* l一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面2 S/ C, c' x1 Y& \% s/ C2 M- O
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) ! O" c3 s# Z3 z3 B4 @+ Q+ [
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)# I. s  B! r+ }
e.g.
( z( B9 y6 Y8 o6 Q3 K  o- ]0 + 4294967295 = 4294967295 (max)
* K5 N7 \, L1 |! O; f1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
