1. output is Novell
2. output is Hello World World
because after 1st printf fork is executed .This creates the child process so child will execute 2nd printf & oncemore by parent process.Hence world is printed twice.

for 2nd question,
o/p - helloworldhelloworld. ( this is the case on linux)
because, execution of first printf statment stores in buffer.
fork , forks helloworld. thats why, its print 2 times helloworld.
In case if u placed "\n" line buffer in first printf .
like : printf("hello\n"); directly prints on standard buffer.
thats the reson it only forks the second printf.
o/p - hello
world world
