so funny, thanks a lot!

/ v% f( }' G7 T

, s9 e2 h# w: L8 z, G9 E3 e' R好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面
- }; X% Q3 f' ~( g2 y0 Y0 ]( fMaximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff)
3 G7 }( B% `: f% f" 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)/ Y# s; _% B8 V5 x" s* _/ m! d
e.g.) F9 Y" ^" V( ~  i
0 + 4294967295 = 4294967295 (max)
% g3 J, \. Y  C# ]' y- v1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
$ e. m: M; V' s4 q4 y- c& m/ Fand so on....1 J$ Z3 b) X1 W% s' r
