 #include <stdio.h>
 #include <stdlib.h>

 int main(void)
 {
         int s[] = {,,,};
         int *p = s;
         int **point = &p;

         printf("s = %d\n",s);
         printf("s[0] = %d\n",s[]);
         printf("p = %d\n",p);
         printf("*p = %d\n",*p);
         printf("*point = %d\n",*point);
         printf("**point = %d\n",**point);

         return ;
 }

执行结果：

 s =
 s[] =
 p =
 *p =
 *point =
 **point = 

由结果可知，**point = *p = s[0]    *point = p = s
