Is that possible to add pointers to each other?

Question

Explain this question, the interviewer ask me this question at the time of interview recently.

Answer 1

you can only add values to pointer address, to access a particular address, and you can subtract a pointer from another pointer and not addition of 2 pointers

Answer 2

There is no possibility to add pointers together. Since pointer contains address details there is no way to retrieve the value from this operation.
