Expected constructor, destructor, type conversion
I get these two errors when I compile
Code:
/home/sterling/CODE/UnorderedList/UnorderedList.cpp|22|error: expected constructor, destructor, or type conversion before ‘&’ token|
/home/sterling/CODE/UnorderedList/UnorderedList.cpp|23|error: expected constructor, destructor, or type conversion before ‘&’ token|
The part of the file that it's telling me about are these two functions -
Code:
//GETTER FUNCTIONS
Node& UnorderedList::Node::getNext() {return next;}
Node& UnorderedList::Node::getPrevious() {return previous;}
I feel like it's telling me that it doesn't recognize Node, but I don't understand why. Node is a nested class in UnorderedList.h. That file is this -
Code:
#ifndef UNORDEREDLIST_H
#define UNORDEREDLIST_H
#include <exception>
class UnorderedList {
public:
class EmptyListException: public std::exception {
public:
virtual const char* what() const throw();
}; //END EMPTYLISTEXCEPTION
class InvalidInputException: public std::exception {
public:
virtual const char* what() const throw();
}; //END INVALIDINPUTEXCEPTION
class Node {
public:
Node(int element);
~Node();
Node& getNext();
Node& getPrevious();
int& getElement();
private:
int element;
Node* next;
Node* previous;
}; //END NODE CLASS
UnorderedList();
~UnorderedList();
void add(int element);
int remove(int element);
void print();
int size();
bool isEmpty();
private:
Node* head;
int count;
};
#endif
I don't see why the exception classes compile fine but Node doesn't. I have tried changing the return from Node& to Node*, changing the return in .cpp to UnorderedList::Node&, and other random things. None have worked though. Can anyone tell me what's wrong? Thanks.
