以下哪项更好/更快？

Question

对于这个具体案例并不重要但是什么是更好的做法，什么会更快？我认为后者对于我读过的两个都不应该对任何大于1的数字进行硬编码，并且还猜测INC会比汇编中的ADD快。虽然我认为前者看起来更好。或者有更好的方法吗？

for (int i = 0; i < CARDS_PER_HAND; i++)
{
    playerHand[i] = getDeck[deckIndex];
    hellmuthHand[i] = getDeck[deckIndex + 1];
    dwanHand[i] = getDeck[deckIndex + 2];
    iveyHand[i] = getDeck[deckIndex + 3];
    negreanuHand[i] = getDeck[deckIndex + 4];
    deckIndex += 5;
}

或

for (int i = 0; i < CARDS_PER_HAND; i++)
{
    playerHand[i] = getDeck[deckIndex];
    deckIndex ++;
    hellmuthHand[i] = getDeck[deckIndex];
    deckIndex++;
    dwanHand[i] = getDeck[deckIndex];
    deckIndex ++;
    iveyHand[i] = getDeck[deckIndex];
    deckIndex ++;
    negreanuHand[i] = getDeck[deckIndex];
    deckIndex ++;
}

Answer 1

真正的答案是，优化是错误的部分，但如果牌组改组，它可以更快一点：

Array.Copy(getDeck, CARDS_PER_HAND * 0, playerHand  , 0, CARDS_PER_HAND);
Array.Copy(getDeck, CARDS_PER_HAND * 1, hellmuthHand, 0, CARDS_PER_HAND);
Array.Copy(getDeck, CARDS_PER_HAND * 2, dwanHand    , 0, CARDS_PER_HAND);
Array.Copy(getDeck, CARDS_PER_HAND * 3, iveyHand    , 0, CARDS_PER_HAND);
Array.Copy(getDeck, CARDS_PER_HAND * 4, negreanuHand, 0, CARDS_PER_HAND);
deckIndex += CARDS_PER_HAND * 5;
