利用typedef定義一個predicate型態的function pointer,傳入為int,傳出為int,雖然不一定得自行用typedef定義,但function pointer很容易寫成很複雜很難懂的程式,所以建議用typedef重新定義。 21行 void print_array(int *beg, int *end, predicate fn) { 宣告print_array最後一個參數為predicate這個function pointer型態,可...
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 3 4Filename : ArrayPassToFu...
