//例子8.14 将n个数按输入时顺序逆序排列，用函数实现
//左指针，右指针
#include
void sq(int* p, int n)
{
	int* pl = p;
	int* pr = p + n - 1;
	while(pl < pr)
	{
		int temp = *pl;
		*pl = *pr;
		*pr = temp;
		pl++;
		pr--;
	}
}
int main()
{
	int a[5] = { 1,4,2,8,3 };
	int* p = a;
	sq(p, 5);
	int i;
	for (i = 0; i < 5; i++)
		printf("%d ", *(p + i));
}

//例子8.18 输入月份号，输出该月英文名，指针数组

#include
int main()
{
	char* month[4] = {"jan","feb","mar","api"};
	int n;
	printf("输入月份：n");
	scanf("%d", &n);
	printf("%s", *(month + n-1)); //数组从0开始
	return 0;
