+ R6 T6 i3 U( ^) w, m% P& n3 K- N好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面5 m( {# G/ _8 z
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
" t) q* }* V* {8 ^+ @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)

$ Z6 v0 a% W, u% W6 M) k4 U# Y0 + 4294967295 = 4294967295 (max)& p. J4 ], {! [" H
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)1 W$ D: u( u+ V  Z* K
and so on....
