好簡單, ICQ 應該係 Visual C++ 寫的 , 而係 Visual C++ 入面- Z5 V/ Q! j* g+ Z5 i4 D+ T
Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) 6 k' x1 \' i* Q2 S: h8 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)0 c% }! |8 v/ s) L% \
e.g.5 U0 l! _/ [  S# F0 B
0 + 4294967295 = 4294967295 (max)
# a, Q$ Q5 L: b, F. D7 j1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow)4 W2 J" ^* j! j8 r+ x/ S
