程序没有问题呀，将二维数组行、列倒置以后再与二维数组相加

#include<stdio.h>

int a[3][3] = { 1,2,3,4,5,6,7,8,9 };
int i, n;
void fun(int d[3][3])
{
    int b[3][3];
    int c[3][3];
    for (i = 0;i <= 2;++i)
    {
        for (n = 0;n <= 2;++n)
        {
            b[n][i] = d[i][n];
            c[n][i] = d[n][i] + b[n][i];
        }
    }
    for (i = 0;i <= 2;++i)
    {
        for (n = 0;n <= 2;++n)
        {
            printf("%2d ", d[i][n]);
        }
        printf("\n");
    }
    printf("\n");

    for (i = 0;i <= 2;++i)
    {
        for (n = 0;n <= 2;++n)
        {
            printf("%2d ", b[i][n]);
        }
        printf("\n");
    }
    printf("\n");

    for (i = 0;i <= 2;++i)
    {
        for (n = 0;n <= 2;++n)
        {
            printf("%2d ", c[i][n]);
        }
        printf("\n");
    }
    printf("\n");
}


int main()
{
    fun(a);

    return 0;
}

二维数组一点都不好玩好不好～～～

#include<stdio.h>

int main( void )
{
    const int a[3][3] =
    {
        {1,2,3},
        {4,5,6},
        {7,8,9}
    };
    
    size_t i,j;
    
    for ( i = 0; i != 3; ++i )
        for ( j = 0; j != 3; ++j )
        {            
            int b[4];
            int sum;
            
            size_t k;
            
            b[0] = i[a][j];
            b[1] = j[i[a]];
            b[2] = i[j[a]];
            b[3] = j[a[i]];
            
            for ( sum = k = 0; k != sizeof (b)/sizeof (*b); ++k )
                sum += b[k];
            
            printf( "%-4d%c",sum,"\n"[ j != 2 ] );
        }
        
    return 0;            
}

上面回复错了，五笔的重复词，正确的是：注意结帖，因为这个论坛有结帖率，你的结帖率过低，以后的求助可能会有问题

谢谢提醒！
