Maximum value for a variable of type "unsigned int" 係 4294967295 (0xffffffff) * ?( U  {4 Z+ d" [
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). ^% g5 [. G7 P
e.g.8 u2 P$ W' W, C$ w' U
0 + 4294967295 = 4294967295 (max)$ m5 d5 E) o& k8 [* C
1 + 4294967295 = 0 + 4294967296 = 0 (because of overflow), s6 L* [& a- h0 ^: Y
and so on...., N3 j) b$ q0 P5 ?3 v/ D7 w2 }
