How to define a global variable in .h file?

[pardxa]

I am trying to keep all global variables in one .h file.here is a example like this:

// stdafx.h

#if !defined(AFX_STDAFX)
#define AFX_STDAFX

#include <stdio.h>
char word[20];

#endif

//main.cpp
#include "stdafx.h"
int main(int argc, char* argv[])
{
strcpy(word,"ok ,you r welcome",20);
printf(word);
return 0;
}

but the result like this:

Linking...
StdAfx.obj : error LNK2005: "char * word" (?word@@3PADA) already defined in console.obj
Debug/console.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.

what should i do, if i intend to keep all global variables in a header file.
