１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296
& ]3 @( I$ _' j8 q將計出黎個數 post 去 ICQ→加入→搜尋; I; b( u% A) w
就發現搜尋結果係........, ?( b$ s) I4 V5 Y) K- r
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面$ Z  {/ g" e+ t) y$ T2 ~  w1 [
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 6 I5 N2 L9 P% \+ Y1 K2 M6 D1 R9 M# D
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)
  t4 j4 C) {9 \, g& Y+ w  \) re.g.
; t; c, l/ \" r0 + 4294967295 = 4294967295 (max)
! t0 X! T0 h3 s! V1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
& L/ ~; x( g# B; @# M3 R& fand so on....
