When a pointer to a particular type (say int, char, float, ..) is incremented, its value is increased by the size of that data type. If a void pointer which points to data of size x is incremented, how does it get to point x bytes ahead? How does the compiler know to add x ...

2.Pass Array to Function C語言 將陣列傳到function時,由於陣列可能很大,若用pass by value的方式傳進function,勢必造成大量copy的動作而降低效能,C語言是靠pointer的方式,將陣列第一個元素的位址以pointer的方式傳進function。 1/* 2(C) OOMusou 2007http://oomusou.cnblogs.com ...
