Java

class Lesson037
{
    public static void main(String[] args) {
        int ma[][] = {{1, 2, 3}, {4, 5, 6}};
        int mb[][] = {{6, 3, 4}, {5, 1, 2}};
        int mc[][] = new int[2][3];

        for (int i = 0; i < 2; i++)
        {
            for (int j = 0; j < 3; j++)
                System.out.printf("%3d", mc[i][j]);
            System.out.print('\n');
        }

        for (int i = 0; i < 2; i++)
            for (int j = 0; j < 3; j++)
                mc[i][j] = ma[i][j] + mb[i][j];

        for (int i = 0; i < 2; i++)
        {
            for (int j = 0; j < 3; j++)
