can you tell me one more thing in if condition the fork will return 0 than how it’s greater than 0 . means how it’s executing the fork condition inside the if condition

@Sagar475 Inside if for parent process fork returns value greater than zero and for child it returns zero . 

Now coming to this particular question after first fork i.e Fork1, child1 goes into first if condition .For 2^nd fork inside 2^nd if block, it will become a  parent process and create child2.

@Isha_99 Correct and simply, we can say that when child process execute fork(inside_child), then for this fork child behave like parent.
