print_array(ia, ia + 3, is_even<int>()); 也和C語言很類似。 function object的優點在於語法較高階,若配合constructor,則比function object更強,在(原創) Function Pointer、Delegate和Function Object (C/C++) (template) (C#)有詳細的討論。
C语言代码很简洁,里面用到了不少的英文缩写。如果不了解这些缩写,程序的第一行都难以理解,更何况后续的学习。举个例子,部分初学者有可能把第一行的stdio写成studio,还不容易察觉。下面列出一些常见的英文缩写,便于初学者理解和记忆,做到事半功倍。 初学者可以在即刻编程的...
答案是D，指向包含5个整型元素的一维数组的指针。
加上typedef后，Pode等价于struct node *。所以Pode *p表示的是struct node **p，即二级指针。直接使用Pode p即可。
