int main()
{
    int a[3][3];
    for (int i = 0; i != 3; i++)
    {
        for (int j = 0; j != 3; j++)
        {
            a[i][j] = i * 3 + j;
        }
    }

    for (int i = 0; i != 3; i++)
    {
        for (int j = 0; j != 3; j++)
        {
            cout << a[i][j] << " ";
        }
        cout << endl;
    }

    int (*p)[3] = a;
    cout << (*p)[0] << endl;
    cout << (*p)[1] << endl;

    cout << *p[0] << endl;
    cout << *p[1] << endl;

    return 0;
}
