Hi All,
I am trying to implement generic link list in c++ .
But getting below error .
Please assist me to correct it.
LinkedList.hpp
LinkNode<E>* head; errr: unknown tpe name ''LinkNode
// LinkNode.hpp
// cplus
//
// Created by Ravi Rathore on 10/12/15.

private:
E elem;
LinkNode<E>* next;
//friend class LinkedList<T>;
};
#endif /* LinkNode_hpp */
