You mean speed? In my opinion, there is no difference in speed between 2 ways. When I compile this array initialization using gcc 5.4.0, this initialization becomes mov instructions when MAX_NUM_UDC=2 and becomes rep stos when MAX_NUM_UDC=32. I think it makes no difference when comparing with memset() Thanks, Quang Minh
