程序代码：

#include<stdio.h>
int main()
{
    int nember1[2][3]={{1,2,3},{4,5,6}} ;
    int nember2[2][3]={{1,2,3},{4,5,6}} ;
    int sum[2][3];
    int i,j;
    for(i=0;i<=1;i++)
    {
        for(j=0;j<=2;j++)
        {
            sum[i][j]=nember1[i][j] + nember2[i][j];
            printf("%4d",sum[i][j]);
        }
    }
    return 0;
}
