LinkedList

Hi, I am trying to implement a simple Linked List. When I declare the class DbLinked, the compiler give me an error:2
\progetto1\main.cpp required from here
Error] 'DbLinked<T>::next' has incomplete type
[Error] declaration of 'class DbLinked<int>
The declaration of the Class is the following:
1
2
3
4
5
6
7
8
9
10
11
12

template<class T>
class DbLinked
{
	//dato: รจ la variabile che contiene l'informazione di un certo record
	T dato;
	DbLinked next;
	public: 
	DbLinked()
	{
	}
	DbLinked(T& elem)
	{
		dato=elem;
	}	
	~DbLinked()
	{
	}
	void add(T& elem )
	{
	}
	bool remove(T& elem)
	{
		
	}
	
	
};


while the fuction main() is written:
1

#include<iostream>
#include "classi.h"
#include<conio.h>
using namespace std;
int main()
{
	int a=5;
	int b=4;
	DbLinked<int>lista(a);
	getch();
	return 0;
}

why the compiler give me this error?

next is an instance of DbLinked, but DbLinked the encompassing class. That's not possible.

you want to do this DbLinked *next; // As a pointer
Don't forget to set the pointer to null in you constructor

It would be better if you would define inside DbLinked some internal class named for example as Node.
