This is my clear() function:



template <typename Object>
void CircleList<Object>::clear()
{
CircleListNode<Object> *p = theBase;

if ( p->next == 0 || p->next ==theBase)

I am currently creating a circular linked class and I am having trouble with the operator= function. This is what I have.


template <class Object>
const CircleList<Object> &...

Ok I got that error to go away but now I'm having a problem in my main.

The error says undefined reference to CircleList<int>::CircleList()

Main File: http://rafb.net/p/C3Y5PO55.html...

Ok so I changed the NULLS to 0's and this is my error message now:

I have these three files and I am obtaining the error message:
NULL Undeclared.

Anyone know...

But I'm doing that because I want to display it again on the next line as the first name.

void Graph::printPath( const Vertex & dest ) const
{
string m;
if( dest.prev != NULL )
{
vector<Edge> e = (dest.prev)->adj;
for(unsigned int i = 0; i< e.size(); i++)...

Well my program is pretty big but if any of you want to look at the files to see if I am going wrong anyplace else here they are:

Actor.cpp http://rafb.net/p/ubeLtL52.html
Actor.h ...

Ok so in graph.h i have


class Graph
{
public:
Graph( ) { }
Graph( std::vector<Actor> * d ) : data(d) { }
~Graph( );
void addEdge( const ActorDB::tag & sourceName, const...

Ok so in graph.h I put


std::vector<Actor> * setActorList();

and in graph.cpp I put


std::vector<Actor> * Graph::setActorList()
{

Where would the setActorList function to set the pointer go?

Ok I believe my problem is that when I create my Graph object I am not passing it the correct reference to the vector.


static Graph actorGraph;

That is how I'm currently calling it which...

Ok I've got a new error now.


void Graph::printPath( const Vertex & dest ) const
{
if( dest.prev != NULL )
{
printPath( *dest.prev );
cout << " was with ";
}

So I'm working on a project that solves the Kevin Bacon problem. The code works fine for a small file size, but I have to read in the entire IMDB movie database file, which contains thousands of...

Ok so here's my problem now....


#include "App.h"

#include "Movie.h"
#include "Actor.h"
#include "ActorDB.h"
#include "MovieDB.h"

Ok so I made actorGraph static. Now I have an error in my actorConnections function:

"undefined reference to Movie::actorGraph"

I'm sure this has something to deal with it being static, so is...

I need one actorGraph for all the movies because this is the Kevin Bacon problem, so I need connections(vertices) between all actors in all movies. I know, this will be a lot of edges.

Yes I do...

This is actorConnections function in my Movie.cpp file:


void Movie::actorConnections(ActorDB::tag a) const
{
for (unsigned i = 0; i <the_cast.size(); ++i)
{...

I'm not too familiar with pointers, but would I change


///The private graph for the Kevin Bacon Problem
mutable Graph actorGraph;

to


mutable Graph *actorGraph;

Is there any way to fix this?

MovieDB.h....
