Hello everyone.

I've been trying to implement a linked list in C++. I found this implementation on the web, where they created a struct for the list's nodes. When trying to add a new node to the list, I get this error:

**List.C: In member function `bool Linked::addNode(Point)':
List.C:23: error: no matching function for call to `Linked::node::node()'
List.H:35: note: candidates are: Linked::node::node(const Linked::node&)**

And here's my Code, and thank you very much.. :)

**List.H**

```
#ifndef _AUXILIARY_H_
#define _AUXILIARY_H_
#include <string.h>
#include <math.h>
class Linked
{
public:
// Constructor: initializes a set of nodes
Linked();
// Linked methods
bool addNode(Point p);
bool removeNode(int index);
bool getNode(int index, Point* p) const;
bool setNode(int index, Point p);
int getNodesCount() const;
// Destructor: delete the set of nodes
~Linked();
private:
// Definition of the nodes on the array of nodes
/*typedef struct _Node* pNode;
typedef struct _Node
{
Point pt;
int index;
Node *next;
} Node;
*/
struct node
{
Point pt;
int index;
node *next;
} *pLinked;
};
#endif // _AUXILIARY_H_
```

**List.C**

```
#include <string.h>
#include "List.H"
Linked::Linked()
{
pLinked=NULL;
}
bool Linked::addNode(Point p)
{
node *q,*t;
int i=0;
q = pLinked;
while (q+i)
{
if ((q->pt.getX() == p.getX()) && (q->pt.getY() == p.getY()))
return FALSE;
q = q->next;
i++;
}
t = new node;
t->pt.setPoint(p);
t->index = getNodesCount();
t->next = q->next;
q->next = t;
return TRUE;
}
bool Linked::removeNode(int index)
{
node *q,*r;
q = pLinked + index;
r = q - 1;
if (q == NULL)
return FALSE;
r->next = q->next;
delete q;
return TRUE;
}
bool Linked::setNode(int index, Point p)
{
node *q;
q = pLinked + index;
if (q == NULL)
return FALSE;
p.setPoint(q->pt);
return TRUE;
}
int Linked::getNodesCount() const
{
node *q;
int count=0;
for( q=pLinked ; q != NULL ; q = q->next )
count++;
return count;
}
Linked::~Linked()
{
node *q;
if( pLinked == NULL )
return;
while( pLinked != NULL )
{
q = pLinked->next;
delete pLinked;
pLinked = q;
}
}
