１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
: a: X; H# B; e; c2 n0 r$ ]將計出黎個數 post 去 ICQ→加入→搜尋
/ Y/ C3 _! j4 c, I; ~6 G就發現搜尋結果係........
5 `$ F4 Z3 {% E- M6 k+ e  B4 Y一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面
" k6 e  H' Z8 y4 X2 M3 |0 W  EMaximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
- A2 z2 Q4 P' p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 j) l) f( o' e8 R+ G0 `6 G& oe.g.
" [- a- f$ q5 t% r" t$ L, S0 + 4294967295 = 4294967295 (max)
& H% b/ ]1 w( D% K1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
