for(int i = 0; i != 10; i++)
for(int i = 0; i < 10; i++)
for(int i = 0; i != 10; ++i)
for(int i = 0; i < 10; ++i)


From the options above, number 3's the best, isn't it?

If possible you should loop downwards to zero, it's usually more efficient that way.

But to answer op, for such a small thing it's best to just unroll it:


i = 0;(loop body)
i = 1;(loop body)
i = 2;(loop body)
i = 3;(loop body)
i = 4;(loop body)
i = 5;(loop body)
i = 6;(loop body)
i = 7;(loop body)
i = 8;(loop body)
i = 9;(loop body)
