Hi Ashu
you are right ! Hello world should be print only ones!
but it's printing twice as when printf executes it does not send data to
output buffer.
so if use \n their or fflush(stdout); after printf ,or see the comment that
I have put in your code, it will print Hello World single times.
Regards,
Pramod

The output of the above program is :
Hello World!I'm the child!
Hello World!I'm the parent!
Why is "Hello World" being printed twice?
Only the parent should print it right?
If "Hello World" is appended with a "\n" the output is...
Hello World!I'm the child!
I'm the parent!
Hello World is printed only once.Can anybody please explain whats goin on?
My guess is this because the stdout isnt flushed before the child is
created.
Please help.
Thanks a lot.
