In a “for” statement, should I use `!=` or `<`?

Question

I\'ve seen both of these two for statements:

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

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

I know they all stop when i reaches 10 , bu

Answer 1

I know they all stop when i reaches 10 , but it seems better to use the second one(I heard).

That is a micro optimization. Use whatever makes more sense (and above < makes more sense).

What is the different?

The 1st version uses the inequality operator !=, and the 2nd uses the less operator <.
