Implement the member function void insertAfterHead(int d) of the LinkedList class . The job of the function is to insert a new node with data d right after the head node. Your header will be

void LinkedList::insertAfterHead(int d)

The function does nothing if called on an empty list.

This is what I tried, it doesn't work. { void LinkedList::insertAfterHead(int d) Node * temp = headPtr; Node * nodeToInsert = new nodeTemp->getNext()); temp->(insertAfterHead); length++; }
