Thread: Help with Linked List

Just started learning Linked List and I am pretty lost. I have started a class but not sure it it is correct. Just need some feed back on if the class is setup right and any additional things about linked list. Every site I have looked at so far has pretty much did and said the same thing and its not helping any. I understand the concept it is just turning it into code.

Code:

#include <iostream>
#include <string>

using namespace std;

#include "swcString.h" //Custom string class

class objList
{
public:
	objList();
	~objList();
	
	objList operator+(objList);

private:
	swcString objName;
	swcString objMaterial;
	int objWeight;
	int objMass;
};

class objNode
{
public:
	objNode();
	objNode(objNode &);
	~objNode();
	void addNewObj();
	void delObj();
	bool emptyObj();
	void traverseObj();
	objList * searchObj();
private:
	objList object;
	objNode *start;
	objNode *next;
	objNode *previos;
	objNode *end;
};

int main (void)
{
	return 0;
}

also when trying to do

Code:

objNode::objNode()
{
}

i get this error:

Code:

ompiling...
main.cpp
Linking...
main.obj : error LNK2001: unresolved external symbol "public: __thiscall objList::objList(void)" (??0objList@@QAE@XZ)
Debug/List.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

List.exe - 2 error(s), 0 warning(s

It is not reconizing my constructor in the class for some reason
