Modify fork3.c so that:

a. The parent process creates two child processes that each print hello to the world. Be sure to tag each child with a unique identifier (like child 1 or child-2).

b. Using the system call sleep(), modify the code so that each child thread will sleep (i.e. not be scheduled on the processor) for a randomly selected value of 1 through 5 seconds.

include #include int pid1-1; int main() if ((pid! = fork())-0) printf C"Hello world from the child. In if (pid1>) printf C"'Hello world from the parent.n")
