Namespace Problem, *sigh*

Hi, Im using namespaces for one of my assignments and its really boggling my mind. Here is my class:

Code:

---


#ifdef _GAMETREE_
#define _GAMETREE_

// My Namespace
namespace Mastadex
{
        // Macros to make my Life Easier
        #define BOARDSIZE 30

        typedef struct Node
        {
                Node *Parent;                                        // Pointer to the Parent Board

                int BoardValue;                                        // The Value of the board
                int BestMove, WorstMove;                // Represents a Numerical Value equal to an Index in the Array of Possible Moves
                int Board[6][5];                                // The Board Itself

                Node *NextMove[BOARDSIZE];                // An Array of Pointers to Board Configs
        };

        class GameTree
        {
                Node *RootNode;                                        // Root Node
                Node *CurrentNode;                                // Current Node that is being Pointed To
                int MoveX;                                                // Recommended Move X
                int MoveY;                                                // Recommended Move Y

                //int EvaluateBoard(int Board[][6]);
                //void ClearTree();
                //void CopyBoard(int ToBoard[][6], int FromBoard[][6]);

        public:

                GameTree()
                {
// NOTHING YET
                }
                ~GameTree()
                {
// NOTHING YET
                }
                //void MapBoard(int Board[][6]);
                //void RecommendedMove(int &X, int &Y);
        };

        void GetLocation(int &X, int &Y, int Board[][6])
        {
// NOTHING YET
        }
}

#endif

---

Here is My Main:

Code:

---


#include "header.h"

int main(int argc, char *argv[])
{
        int board[5][6];
        int loc1, loc2;

        Mastadex::GetLocation(loc1, loc2, board);

        return 0;
}

---

In the main, im getting this error at the GetLocation functioncall in VS.NET: error C2653: 'Mastadex' : is not a class or namespace name

Ignore the fact that this class does nothing, im just trying to get it compiling right now. This is my first time dealing with namespaces, I have no idea how to fix this. Help?

EDIT: Im using Visual Studio .NET 7.1

Code:

---

#include "header.h"

---

Code:

---

#ifdef _GAMETREE_
#define _GAMETREE_

---

You sure your header file with the class is called header.h?

Did you ever consider closing that program, and creating another simple program to test out namespaces? You might even want to create a program called something like Tester. Then, whenever you need to test something out, you won't have to go to the trouble of creating a new project--you can just open Tester and write some code you want to test out.

Here is a simple example of a namespace:

Code:

---

#include <iostream>
using namespace std;

namespace Mastadex
{

        void GetLocation()
        {
                cout<<"hello"<<endl;
        }

}

int main()
{
        Mastadex::GetLocation();

        return 0;
}

---

Or, divided into multiple files it would look like this:

test.h
--------

Code:

---

#include <iostream>
using namespace std;

namespace Mastadex
{

        void GetLocation()
        {
                cout<<"hello"<<endl;
        }

}

---

main.cpp
-----------

Code:

---

#include <iostream>
#include "test.h"
using namespace std;

int main()
{
        Mastadex::GetLocation();

        return 0;
}

---

Umm maybe try using ifndef instead :)

Quote:

---

#ifdef _GAMETREE_
#define _GAMETREE_

---

I assume this is an inclusion guard. You should use ifndef instead, only include it if it has NOT been defined yet.

Quote:

---

#define BOARDSIZE 30

---

For constants use the const keyword instead, it' much safer and has type checks:

Code:

---

const int BOARDSIZE = 30;

---

Yea, my guess is your whole problem being you said #ifdef, and not #ifndef.
