How to create child process using fork() || Duplicate Process

i am very grateful to you,,...this is the first time i am posting any comment ...i love you sir ....its really helpful ..i appreciate your service ..god bless you .

Sir in my output in parent block parent id is always printing 1. why is that ? and my outputs are also fixed like first child block is printing and then parent block they are not getting mixed like in yours. Does it have to do something with fact that i am working in zsh bash?

sir i have implemented the same code but its showing error near else

👍👍👍

plz use English throughout the video.I don't understand hindi

You said q is the pid of the child and fork() returns the value of pid of child. However you said if q==0 is true then it is the child process. Then how is q printed to be 93? Shouldnt it be printing 0?

the code for the exercise:
if(q==0)
fork();
only this part should be added,is this correct sir??

Does execution always prefer parent process first?

You're a lifesaver sir ! Great explanation

Thanks a lot Sir

i am getting different id at some time and same id at some time. for same program like
before fork
PARENT My child's id is 3025
PARENT I am parent having id 3024
Common
CHILD I am child having id 3025
CHILD My parent's id is 1461
Common

PLEASE EXPLAIN

int main()
{
pid_t p1,p2;
printf("Before Creating Child \n");
p1=fork();
if (p1==0)
{ printf("this is child process p1 having pid %d \n",getpid());
printf("parent id of child process p1 is p=%d \n",getppid());
p2=fork();
if (p2==0)
{ printf("this is child process p2 having pid %d \n",getpid());
printf("parent id pp1 of child process p2 is p=%d \n",getppid());
}
else {
printf("this is parent process pp1 having pid %d \n",getpid());
printf("pid of child process p2 is %d \n",p2);
}
}
else {
printf("this is parent process p having pid %d \n",getpid());
printf("pid of child process p1 is %d \n",p1);
}
}

This is code to create child process inside child process
