Print 2-D Array in clockwise expanding spiral from center

Question

I have an guaranteed to be a perfect square matrix. I want to start at the center of the matrix in this case it would be matrix[2][2], I know h

Answer 1

    int radius = 0;
    int i = centerX;
    int j = centerY;
    Debug.Log("i=" + i + "; j=" + j);
    ++i;
    radius += 2;
    while ((i < dimm) && (i >= 0))
    {
        for (int c = j; j < c + radius; j++)
            Debug.Log("i=" + i + "; j=" + j);
        --j;
        --i;
        for (int c = i; i > c - radius + 1; i--)
            Debug.Log("i=" + i + "; j=" + j);
        if (i < 0)
            break;
        else
            Debug.Log("i=" + i + "; j=" + j);
        --j;
        for (int c = j; j > c - radius; j--)
            Debug.Log("i=" + i + "; j=" + j);
        ++i;
        ++j;
        for (int c = i; i < c + radius; i++)
            Debug.Log("i=" + i + "; j=" + j);
        radius += 2;
    }

This Code will output counterclockwise squared matrix (dimm X dimm) indexes from custom center(CenterX, CenterY); and end up, if it came out of matrix size.
