 指针数组的一个重要优点在于，数组的每一行长度可以不同

测试：

#include <stdio.h>int main(void){		int *pint[3];	int a[] = {0,1};	int b[] = {2,3,4};	int c[] = {5,6,7,8};	*pint = a;	*(pint + 1) = b;	*(pint + 2) = c;	PRintf("%d/n",*pint[1]);	printf("%d/n",(*pint)[1]);	printf("%d/n",*(pint + 1)[1]);	printf("%d/n",(pint + 1)[1][1]);	printf("%d/n",*(pint + 1)[2]);//	printf("%d/n",*(pint + 1)[2][1]);	printf("%d/n",*(pint + 1)[3]);	printf("%d/n",(*(pint + 1))[1]);	printf("%d/n",(int) pint);	printf("%d/n",(int) pint[1]);	printf("%d/n",pint[1][1]);//	printf("%d/n",*pint[1][0]);//	printf("%d/n",(*pint[1])[0]);	return 0;}
