Question

I am trying my hands on sample codes from a book, and so I am not entirely sure what I may have wrong in the header file I have so far.

I keep getting the following error messages.

Error 2 error C2061: syntax error : identifier ‘streambuf’
Error 1 error C2504: ‘ios’ : base class undefined
Error 5 IntelliSense: identifier “streambuf” is undefined

// StdAfx.h HEADER FILE 
**************************
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//

#pragma once
#include <iostream>
#include <strstream>
#include <iomanip>
#include <ios>
#include <stdio.h>
#include <tchar.h>
#include "targetver.h"


// Conios HEADER FILE 
**************************

#include "Stdafx.h"



class Conios :virtual public ios{
protected:
public:

    Conios(void);
    ~Conios(void);
     Conios(streambuf* Buffer);
};

Answer 1

ios is in the std-namespace. So either use use namespace std; or extend from std::ios instead of just ios.

If you are using use namespace use it only in your implementation-files like *.cpp or *.cxx, do not write use namespace ... your header files – ever!.

And the same goes for streambuf.
