Out put of this will be n because in while loop you are assigning the value p2 from p1 and incriminating the both pointers p1 and p2 due to this your pointers p1 and p2 will point to the null. So when you try to pointer p2 it will point to nothing and it will print only n.

Copying will happen but pointer will increment and point at the end, so will not print anything as you have already hit at the end.
