１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 , y' n+ {$ P5 |: J# ^5 X- G8 q
將計出黎個數 post 去 ICQ→加入→搜尋
, A9 [5 V4 M' I$ z8 o* q就發現搜尋結果係........, |% d" t) |' C
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面
; ~: w. d! i" u7 ]3 l, YMaximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 3 i+ \9 _4 B5 J" t5 L9 K4 E
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)# Z% S. g6 {- E& \4 E% Q1 e7 Z. g; {$ i
e.g.
; f7 d$ u2 w) d! E0 + 4294967295 = 4294967295 (max)& b! Q% i% K- \
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)

我都學過少少visual basic,,+ z: K% t. }/ x) K
不過basic始終係basic,,唔夠呢位大哥咁勁,,!
