Custom class problem (strings)

[Dili]

hey all!

this might look silly but i'm having problems using strings in a custom class.

here is the code:

word.h

#ifndef WORD_H
#define WORD_H

class Word
{
	public:
		Word( string );
		string get( void );
	private:
		string i;
};

#endif 

word.cpp

#include "word.h"
#include <string>

Word::Word(string ii)
{
	i = ii
}

string Word::get( void )
{
	return i;
}

main.cpp

#include "word.h"
#include <string>
#include <iostream>

using namespace std;

int main()
{
	Word c( "3" );

	cout << c.get();
	cin.get();

}

and here are the lovely errors:

Error 1 error C2460: 'Word::string' : uses 'Word', which is being defined word.h 7

can anyone make sense of these errors and why they are occurring? everything looks fine to me syntactically. am i missing includes in the word.h file?

thanks!

The word.h file requires #include <string> after your #define directive. You can remove #include <string> from word.cpp because it then comes along with word.h.

thanks for your reply!

however adding #include <string> after #define in the word.h only adds more errors :( i tried adding the include when i was debugging and it still didn't solve the problem. by the way i'm using Visual Studio 2008 to complie.

could it be anything else?

[psault]

Oh yes, in every file that you did not use "using namespace std" you need to change string to std::string because string is part of the std namespace and cannot be seen by the compiler without that scope operator.

never mind!

using namespace std;

that was missing. i feel like such a noob! :D

thanks for your help!

[psault]

Don't fret. Many many people advise against using "using namespace std" and suggest that you use the scope operator instead. That means typing std:: in front of every function that is within the std namespace you are trying to access.
Kind of a pain, but it is "the point of namespaces" to allow for duplicate identifiers wrapped in different namespaces without getting a compiler error.

I have a new lovely error, is unknown to you....

I think, maybe my problem message is so strange as it says:

[code=cplusplus]Error: Error: Unresolved external 'WORD::get( void )__stdcall' referenced from MAIN.OBJ[/code]

what's a problem?
