有定义语句：int*p[4]；以下选项中与此语句等价的是( )。
A) int p[4]；
B) int **p；
C) int*(p[4])；
D) int(*p)[4]；
参考答案：C
解析： int *p[2]；首先声明了一个数组，数组的元素是int型的指针。int(*p)[2]；声明了一个指针，指向了一个有两个int元素的数组。其实这两种写法主要是因为运算符的优先级，因为[]的优先级比*高。所以第一种写法，p先和[]结合，所以是一个数组，后与*结合，是指针。后一种写法同理。

I offered to help her eat, and although she too was uncomfortable about 11 it, she did. The experience was pleasant, and she and I 12 close in a short period of time. 13 the end of the five-hour trip, my heart was fully 14 , and the time was 15 better spent than if I had just sat by myself. I was very glad I had reached beyond my comfort zone to sit next to Kathy and feed her. 16 sometimes flows beyond human borders and dissolves the fears 17 keep us separate. When we stretch to serve another, we grow to live in a larger, more 18 world. Help me move 19 the small self so I can connect with the hearts of others.
