Singly linked list

So recent, I started to learn linked list in class and I am confused. She did a whole explanation and some examples, but it doesn't make sense. So for example I have a header file for the class Node and class AnyList.
I have a few functions that I need to implement, but it's a bit difficult for me. One of my functions is suppose to delete the last node of the list.

So this is the Header file:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

41
42

#ifndef ANYLIST_H
#define ANYLIST_H

#include<iostream>
#include <string>				
using namespace std;

class Node
{
public:
    Node() { next = nullptr; }
    Node(const string& theData, Node *nextNode) : data(theData), next(nextNode){}
    Node* getNext( ) const { return next; }
    string getData( ) const { return data; }
    void setData(const string& theData) { data = theData; }
    void setNext(Node *nextNode) { next = nextNode; }
	~Node(){}
private:
    string data;		
    Node *next;		//pointer that points to next node
};


class AnyList
{
public:
	AnyList();	

	void insertBack(const string& newData);

	void print() const;

	void destroyList();

	~AnyList();

	/*************************************************************************/

	// Declaration of function getFirstElement
	Node getFirstElement() const;

	// Declaration of function deleteFirstNode
	string deleteFirstNode(const AnyList& list);

	// Declaration of function deleteLastNode
	string deleteLastNode(const AnyList& list) const;

	// Declaration of function replaceData
	string replaceData(const AnyList& list) const;


private:
	Node *first;			//pointer to point to the first node in the list
	int numOfItems;		//keeps track of number of nodes in the list
};

#endif 



And this is the implement file (.cpp):
