wen u do frok in ur code, the pr gets duplicated. so that line wher fork is invoked is also in both the processes. nw in parent code it will return pid of child & in child code it will return 0.
getpid will always return the pid of the pr. so obviously it will return pid of the child in the child pr. is it clear ..
