Header file headache
Author
Im trying to learn how to use header files with classes. Im using a book but I cant figure out why I always get this error
error C2653: ''BoardClass'' : is not a class or namespace name
Error executing cl.exe.
Here is the code from my main:
#include
#include "Board.h"
int main() {
BoardClass GameBoard;
GameBoard.DrawBoard();
return(0);
}
from the header file:
#ifndef _BOARDCLASS_
#define _BOARDCLASS_
#include
class BoardClass {
public:
void DrawBoard();
};
#include "Board.cpp"
#endif
and board.cpp:
#include
void BoardClass::DrawBoard() { //error here
cout << "Draw Board!";
}
I can''t figure out for the life of me why this happens, I have a decent sized project in school I did using header files, but I dont get the error there and I can''t figure out why. This is killing me, any help would be greatly appreciated, thanks.
Just trying to get the basics down but ther
You should never #include a .cpp file
It should look like this;
//board.h
#ifndef BOARD_CLASS
#define BOARD_CLASS
class BoardClass {
public:
void DrawBoard();
};
#endif
//board.cpp
#include "board.h"
void BoardClass::DrawBoard()
{
//do something
}
//main.cpp
#include "Board.h"
int main() {
BoardClass GameBoard;
GameBoard.DrawBoard();
return(0);
}
////////////////////////
I don''t know where you''re getting the "#include" part by itself - that''s not needed or used. Also, like I said, never include .cpp files.
Hope that helps

It should look like this;
//board.h
#ifndef BOARD_CLASS
#define BOARD_CLASS
class BoardClass {
public:
void DrawBoard();
};
#endif
//board.cpp
#include "board.h"
void BoardClass::DrawBoard()
{
//do something
}
//main.cpp
#include "Board.h"

GameBoard.DrawBoard();
return(0);
}

It looks like you are trying to include board.cpp in board.h... you should be doing the opposite. Board.h should be included in board.cpp like so ''#include "board.h"''. Another thing which may or may not help, but is something to try if the above does not help, is your
#ifndef _BOARDCLASS_
#define _BOARDCLASS_
statements... I always write mine like
#ifndef BOARDCLASS_H
#define BOARDCLASS_H
I hope one of these ideas helps out... post back if they dont.
#ifndef _BOARDCLASS_
#define _BOARDCLASS_

#ifndef BOARDCLASS_H
