１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 ( E+ p  z; ~' T! p, R" f
將計出黎個數 post 去 ICQ→加入→搜尋  u* `2 r2 ]& t1 g% W0 ^
就發現搜尋結果係......... p5 |. y1 {/ `9 N3 p2 g: 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+ V8 U1 t0 y' k# t1 r
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) - z: [9 u7 j/ x0 \' |6 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)$ \( N) Z7 N& a# I% E, V& f
e.g.% j- [. @( a* x/ _/ V2 M" L9 u
0 + 4294967295 = 4294967295 (max)3 b. N: z0 E( m7 P1 N$ _6 R- D1 A) V
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)/ p# R. E' `; e# x& U
and so on....( E- I. R5 W# W" F& U1 ?
