It has to at some point ask the OS to write characters to a file or console.  That much is certain.

Yeah, that is certain but I am just trying to know what exact system call does it use for Windows platform for which one is WriteFile(..) function.

It might even be somewhat compiler dependent.  This isn't something that a programmer really should be worrying about.  May I ask what the motivation for this question is?

Yeah, so the reason is that I am currently taking an Operating Systems class and was curious about this.
