利用指针访问二维数组，然后输出指定位置元素
#include <stdio.h>void main()
{
int a = {1,3,5,7,9,11,13,15,17,19,21,23};
int (*p),i,j;
p = a;
printf("i = ");
scanf("%d",&i);
while(i > 2 || i < 0)
{
printf("i = ");
scanf("%d",&i);
}
printf("j = ");
scanf("%d",&j);
while(j > 3 || i < 0)
{
printf("j = ");
scanf("%d",&j);
}
printf("a[%d, %d] = %d\n",i,j,*(*(p+i)+j));
}
