B2B::NodeNFromEnd

Second post in the series Back to Basic

Display the Nth Node from the End

void findNfromEnd(int nodeNum){
	node *ptr1, *ptr2;
	ptr1 = ptr2 = head;
	for(int i=0; i< (nodeNum-1) ; i++){
		ptr1 = ptr1->next;
	}
	while(ptr1->next != NULL){
		ptr1= ptr1->next;
		ptr2 = ptr2->next;
	}
	cout << "Nth Element from End: " << ptr2->data << endl; 
}
