I'm getting an error in programming a simple text based rpg in VC++. Here's the code that has the error:


// armor.h

#include <string>

struct armor
{
	std::string name;
	int armorRating;
};

And here's the error i'm getting:


1>c:\documents and settings\ian\my documents\visual studio 2005\projects\rpg_1\rpg_1\armor.h(6) : error C2011: 'armor' : 'struct' type redefinition
1>        c:\documents and settings\ian\my documents\visual studio 2005\projects\rpg_1\rpg_1\armor.h(6) : see declaration of 'armor'

Any help would be appreciated.

Try this..

armor.h

#include <iostream>#include <string>using namespace std;class armor{    string name;    int armorRating;};

Try adding header guards, i.e.:

// armor.h#ifndef ARMOR_H#define ARMOR_H#include <string>struct armor{	std::string name;	int armorRating;};#endif // #ifndef ARMOR_H

I'm guessing this will solve the problem.

Be sure to do this for your other header files as well.

*** Source Snippet Removed ***

It's generally considered bad form to put 'using' declarations in header files, as it pollutes the files that include the header.

In any case, I don't think that's the solution to the OP's problem. Your example actually doesn't change anything, other than including <iostream> unnecessarily and changing armor's default privilages.

DOH! How could I forget the inclusion guards?! Thanks

Yes, I would think it is the lack of inclusion guards. That is what it seems like the error is saying.
