Pointers and function

Question

Comments

I also chose option D but given key was A

@joshi

before poping , we have stored the address of "j" in main function, so , poping "foo" will matter ?

---

but value at that address is no more alive..

actually it totally depend on compiler, what it do to the value after the activation record is popped out

Answer 1

The correct answer is 2,2

Even though activation record deletion deletes j variable, since we've already stored the memory location (address of j) in p variable of main, it's accessible even after deletion of activation record. Suggestions/improvements are welcomed

Answer 2

it should give compilation  error because function "foo" is not declared before its use.
 so option c is correct
