１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
* v+ Y3 C8 t- ]/ m9 E將計出黎個數 post 去 ICQ→加入→搜尋
( @- Y4 ~% Z/ \5 w就發現搜尋結果係........
+ i3 T5 }# z( U( p$ h4 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& w/ O) Y$ w9 I7 c$ |  \
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)   y, A' G/ W) `- A8 L9 Y
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)4 z; J: C6 N+ g1 ]- ^
e.g.) r0 F) {" C4 W) r5 O" T2 H/ `* P* l7 P
0 + 4294967295 = 4294967295 (max)" d8 f, z& [4 |) q% H
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)+ c3 b" _+ B0 U7 M$ y) @
and so on....
