１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 : n( P. t/ E  \
將計出黎個數 post 去 ICQ→加入→搜尋  r1 }' A% m% T$ A1 l" x* [
就發現搜尋結果係........4 a9 z3 \/ \; d% D. A
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面0 P' W: a: b! N! \' p$ j
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 3 W: a0 w" p0 \) Y8 n/ C
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)7 l6 z% Y; t4 N( N3 e/ [2 e) F
e.g.
/ u; g, S( V' A7 a5 i; E8 s3 C0 + 4294967295 = 4294967295 (max)  R4 @  I% g- J5 r
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)# W% O4 ]' W4 y
and so on....$ n8 }. o) e5 M" T
