I am facing a problem with my linked list class, I have created the interface and implementation files of the class, but when I build it, this error occurs: "invalid use of template name 'LinkedList' without an argument list". here's my interface file:
#ifndef LINKEDLIST_H
#define LINKEDLIST_H
template <typename T>
struct Node{
T info;
Node<T> *next;
};
template <typename T>
class LinkedList
{
Node<T> *start;
Node<T> *current;
public:
LinkedList();
~LinkedList();
};
#endif // LINKEDLIST_H
and this is my implementation code:
#include "LinkedList.h"
LinkedList::LinkedList()
{
start = nullptr;
current = nullptr;
}
LinkedList::~LinkedList()
{
}
Write it like this:
template<typename T>
LinkedList<T>::LinkedList()
{
start = nullptr;
current = nullptr;
}
And similarly for other member functions. But you'll run into another problem - declarations and definitions of a template can't be separated to different files.
