Question 1: why output is "hello". so printf is buffered function, as everyone knows who use linux/unix, every process open 3 file by default, and these are STDOUT, STDIN, STDERR, internally this program has STDOUT opened, and this "hello" is given to buffer in kernel thru write system call, and kernel driver write this to STDOUT, which is your console, that's the reason you get the output on console.
Question 2: even a new born child knows.
