And p1->next and head->next are also at the same memory location (after we say p1=head), and so are the other next pointers. So, why does setting p1 to nullpointer (or any other value) does not effect head. But, setting p1->next to nullptr, effect head?

For inserting the node at the end we simply copy the address of the node to be added to the last node. And we make the newly added node as null. We can also add an element at the start. We replace the head node with a new node. And we put the address of the next node in our head node.
