Fork() returns 0 to the child process and some +ve value to the parent process.

So Gate will be printed by the child and 2016 will be printed by the parent.

Now order of execution cannot be determined..any of them can execute at first. So a and b are possible.

---

Note: If we don't write exit(0) in the if statement then both the child and parent will print the "2016". so this exit(0) statement makes the child to not print the "2016"

Answer 1

both A and B are correct because the order of child and parent is not known.

Answer 2

Answer Will be 2, the order in which CPU execute either parent or child is nondeterministic.
