数组问题

# include <stdio.h>
# define A 8
# define B 12
# define C 0//C的赋值和D的赋值，决定于要算从C到D之间的数组数！例如C=0，和D=7就是算8组数组的列之和！
# define D 7
int main(void)
{
    int i, j ,total;
    int arry[A][B] = {
        {3,1,0,0,0,1,0,0,0,0,2,0},
        {0,0,0,0,1,1,0,0,0,3,1,1},//  2  2  0  1  3  1  3  2  1  5  3  5
        {0,0,0,0,0,0,3,0,0,1,1,2},
        {0,1,0,1,2,0,0,1,0,1,1,0},
        {2,1,0,0,0,0,0,1,1,0,0,2},
        {1,1,0,1,0,1,1,0,1,1,0,0},
        {1,0,0,1,0,1,1,1,1,0,0,1},
        {1,0,0,0,3,0,1,0,1,0,1,0}
    };
       for(j = 0; j < B; ++j)
    {
        total = 0;
        for(i = C; i <= D; ++i)
        {
            total += arry[i][j];
        }

        printf("%3d", total);

    }
    putchar('\n');

    return 0;
}
//输出结果：
  8  4  0  3  6  4  6  3  4  6  6  6!
这俨然是个数组！怎么把这结果赋给数组，就是组成新的数组！并且能输出和运算！

    putchar('\n');

    return 0;
