输入一个数组a[5][5], 最中间的位置存最大数，其余四个角分别放从小到大的最小的四个数？
#include<stdio.h>

void main()
{
    void tz_(int (*p)[5], int n);

    int a[5][5], i, j;

    printf("please input the array:\n");
    for (i = 0; i < 5; i ++)
    {
        for (j = 0; j < 5; j ++)
        {
            scanf("%d", &a[i][j]);
        }
    }

    tz_(a[0],5);                  ////这个地方始终被报错，真的搞不懂咯，怎么咯？

    printf("please input the new array:\n");

    for (i = 0; i < 5; i ++)
    {
        for (j = 0; j < 5; j ++)
        {
            printf("%4d", a[i][j]);
        }
        printf("\n");
    }
}

}

   兄弟些我弄出来咯哈
