１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 - J0 u7 @! b( [8 u* W8 V! @
將計出黎個數 post 去 ICQ→加入→搜尋. C6 T( e2 W3 g3 p0 c$ B# D
就發現搜尋結果係........3 U9 _. ]# t1 [% p) n7 B
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面) [- U! w2 E) R
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 7 |6 w. E) k% a9 \% k6 l2 f1 s
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)/ @  M1 _2 X* a8 R; W. x8 y" j% S2 C2 G
e.g.5 ~. X0 ^$ ~* d- [* A' H' F
0 + 4294967295 = 4294967295 (max)1 f8 @5 e& J% u, K, Y" m% v1 ]
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)$ q+ E. O" T; o* Q& y: o5 C
and so on....
