I cannot figure out why this piece of code is not working, when trying to compile it says that "error: expected constructor, destructor, or type conversion before ( token doublylinkedlist::Node::Node(&data)"... i do not know what i am doing wrong private: class Node { public: Node(const string &data){} ~Node(); Node* next; Node* prev; string *data; }; Node* head; Node* tail; Node* current; };

template doublylinkedlist::Node::Node(&data) { this->next =nullptr; this->prev =nullptr; }
