Question
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++;
}
Explanation / Answer
void LinkedList::insertAfterHead(int d) if(headPtr != NULL) { Node *nodeToInsert = new Node(d); nodeToInsert->setNext(headPtr->getNext()); headPtr->setNext(nodeToInsert); length++; } }
