        {
                printf(")Parent \n");
                printf("i when 0 \n ");
                printf("Getpid : %d getppid : %d\n",getpid(),getppid());
                printf("\n");
        }

        elseif(i==1)
        {
                printf("Child \n");

        }

        else
        {
        }
}






int pfork(int x)
{
        int j;
        for(j=1;j<x;j++)
        {
                if(fork()==0)
                {
                        //sleep(3);return j;
                }

        return 0;
}


Output:
