int a[3] [4]={
     {1,3,5,7},
     {9,11,13,15},
     {17,19,21,23}
    };
    main()
    {
         int i,(*b)[4];
           b=a+1;                  /* b指向二维数组的第1行, 此时*b[0]或
                                     **b是a[1][0] */
         for(i=1;i<=4;b=b[0]+2,i++)/* 修改b的指向, 每次增加2 */
           printf("%d\t",*b[0]);
         printf("\n");
         for (i=0; i<2; i++) {
           b=a+i;                  /* 修改b的指向,  每次跳过二维数组的
                                      一行 */
           printf("%d\t",*(b[i]+1));
        }
         printf ("\n");
     }
    程序运行结果如下:
     9    13   17   21
