１個好得意既野**

CHUNGYIP!

用計數機將你既icq number + 4294967296 ) E& t9 |/ f  M6 n0 W
將計出黎個數 post 去 ICQ→加入→搜尋3 M# C4 u  }- V! T' b
就發現搜尋結果係........8 S; d: w! W- s$ X4 K
一個你都識既人!!!!

好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面- T- J& V) ^$ a2 g$ o
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) ! s: P- R1 _" h- _/ A4 W, @$ O
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)
# P; c) V  E" w) ]& R) M+ G0 Je.g.) R4 T) y5 h* Y8 J* u
0 + 4294967295 = 4294967295 (max)
- E1 v0 n7 t  ]1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
9 ^+ Y% C3 Y5 {0 B) band so on....  r7 _7 }, s! m' a- C
