好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面
5 p! M; B( ^6 e9 }Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) & |) A5 b: ^3 s/ z6 j' C; D9 N
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)
. r$ r- T2 C  Q( m, O$ e) We.g.- D- z8 F$ H' E, l$ u" d, l
0 + 4294967295 = 4294967295 (max)
! y! O2 N) p% Q; a  t7 Z1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)
( ^- B- s, g  h% f; T9 Wand so on....
