string not recognized in header file

[genik]

I'm just learning c++ now, so the question might be stupid, but... I didn't find any information with search or google.

I'm using MS Visual C++ 6.0. I made a new class with "Insert - New class", and I try to specify the class features. For some reason I get 3 compiler errors when trying to compile the code:

c:\dir\test\test\car.h(16) : error C2146: syntax error : missing ';' before identifier 'itsName'
c:\dir\test\test\car.h(16) : error C2501: 'string' : missing storage-class or type specifiers
c:\dir\test\test\car.h(16) : error C2501: 'itsName' : missing storage-class or type specifiers

I cannot understand why a string is not recognized. Does anybody have any idea?

The actual code is here:

// car.h: interface for the car class.
//
//////////////////////////////////////////////////////////////////////

#if !defined(AFX_CAR_H__7D0E8056_D7F6_4086_A263_41FD17B8F1BB__INCLUDED_)
#define AFX_CAR_H__7D0E8056_D7F6_4086_A263_41FD17B8F1BB__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

class car
{
public:
car();
string itsName;
int itsDoors;
int itsCylinders;
int itsEnginesize;
char itsName;
virtual ~car();
};

#endif // !defined(AFX_CAR_H__7D0E8056_D7F6_4086_A263_41FD17B8F1BB__INCLUDED_)

How? Using what? A book? An online source?

Your not going to learn C/C++ very easily if your trying to piece information together off the internet. You should probably have a book for beginners on C/C++. If you have one that is any good at all it will walk you through learning about "types" etc.

c:\dir\test\test\car.h(16) : error C2146: syntax error : missing ';' before identifier 'itsName'

public:
car();
string[/red] itsName;

There is no type "string". There are other errors as well but posting these errors in a forum is probably not the best way to learn C/C++ as i stated earlier.

Thanks for the reply. I'm learning with a book called "C++ an introduction to programming" (Adams, Leestma, Nyhoff). The code which I posted was mainly created by MS VC++ 6.0, the only thing I added was

public:
car();
string itsName;
int itsDoors;
int itsCylinders;
int itsEnginesize;
char itsName;

and this was copied directly from the book. Therefore I would have assumed that it also works.

Ok, so there's no string data type, knowing that is a step forward. There are string objects anyway, right? I would be grateful to get some pointers how to specify the class containing a string object. There must be a way, I would assume.

Just out of curiosity, what were the other errors?

Well, I got it working now. I had tried before to add

using namespace std;
#include <string>

but it didn't work. By googling a little I found out that I have to add

#include <iostream>

(or some other include) before that. I also removed the line

char itsName;

which produced an error.

Ok my post is not worded correctly, sorry.

The error means there is no &quot;string&quot; type available at compile time. I did not mean to state that there was absolutly no &quot;string&quot; type, but when i re-read my post that is actually what it says. My bad.

anyway the &quot;string&quot; type is part of the STL so if your book is trying to teach you how to use it, there should be sample code that shows something like:

#include <string>

using namespace stl;

you must be missing those parts.

Again sorry for the messed up post.
