I see people using "ios::sync_with_stdio(0); cin.tie(0); cout.tie(0);" I personally use "ios::sync_with_stdio(0); cin.tie(0);" without the "cout.tie(0);". What is the difference? Is the first option faster than the second?

coutis not tied to anything by default. So,cout.tie(false)is useless.Then why do people still use it?
Because they saw it from another person who also doesn't know that it's useless, and they keep using it without noticing because it does nothing — not even any trouble.
Oh, I get it, they are just using it because other mindless blokes are using it too.
