C++ Variable Scope Issues - c++

Question

I'm trying to implement a singly linked list in c++ and I'm running into a lot of scope issues and I'm not sure why. I'm getting errors like LinkedList.cpp:28:11: error: ‘class LinkedList’ has no member named ‘current’ if(this->current == NULL)
Here's my .h file
#ifndef LINKEDLIST_H
#define LINKEDLIST_H
class Node
{
friend class LinkedList;
private:
int data;
Node* next;
Node* getNext() { return this->next; };
public:
Node() { data = 0; next = NULL; };
void setData(int data) { this->data = data; };
void setNext(Node* next) { this->next = next; };
};
class LinkedList
{
private:
Node* head;
Node* current;
public:
LinkedList() { head = current = NULL; };
//LinkedList(const LinkedList &l)
//TO DO: Destructor
void next();
void reset();
void append(int data);
void replaceData(int data);
void removeNode(int data);
void removeLast();
bool reset();
void operator++() { next(); };
};
#endif
and here is my cpp file (There my be more issues, especially with the implementation of the LinkedList, but I'm more concerned with the current compilation errors)
#include "LinkedList.h"
#include <stddef.h>
void LinkedList::next()
{
if(current != NULL)
{
current = current->next;
}
}
void LinkedList::reset()
{
if(head != NULL)
{
current = head;
}
}
void LinkedList::append(int data)
{
Node* newNode = new Node();
newNode->setData(data);
newNode->setNext(NULL);
reset();
if(this->current == NULL)
{
this->head = newNode;
}
else
{
while(this->current->getNext() != NULL)
{
this->current = this->current->getNext();
}
this->current->setNext(newNode);
}
}
void LinkedList::removeNode(int data)
{
this->current = this->head;
if(this->current == NULL) return;
if(this->current->getNext() == NULL)
{
delete this->current;
this->head = NULL;
}
else
{
Node* previous;
do
{
if(this->current->getData() == data) break;
previous = this->current;
this->current = this->current->getNext();
} while(this->current != NULL);
previous->setNext(this->current->getNext());
delete this->current;
}
}
void LinkedList::removeLast()
{
this->current = this->head;
while(this->current->getNext() != NULL)
{
this->current = this->current->getNext();
}
delete this->current;
}
I realize I'm more than likely missing something so incredibly obvious, but I cannot figure this out to save my life.

Answer 1

void reset();
bool reset();
function cannot be overloaded by return type.
void LinkedList::removeNode(int data)
{
if (this->current->getData() == data) break;
}
Your node class doesn't have a getData() function.
I've successfully compiled your code by fixing those 2 issues Live Demo.
If that isn't enough, then perhaps you are probably not including the LinkedList header at all.
