程序代码：

#include<stdio.h>
void change(int(*p1)[3], int(*p2)[3])
{
    int i, j;
    for (i = 0; i < 3; i++)
        for (j = 0; j < 3; j++)
            *(*(p2 + j) + i) = *(*(p1 + i) + j);
}

void print(int(*p)[3])
{
    int i, j;
    for (i = 0; i < 3; i++)
    {
        for (j = 0; j < 3; j++)
            printf("%d ", *(*(p + i) + j));
        printf("\n");
    }
}

int main()
{
    void change(int(*p1)[3], int(*p2)[3]);
    void print(int(*p)[3]);
    int a[3][3] = { {0,1,2},{3,4,5},{6,7,8} };
    int b[3][3];
    int(*x1)[3], (*x2)[3];
    x1 = a;
    x2 = b;
    change(x1, x2);
    print(x2);
    return 0;
}
