Too many types in declaration

Hi,
I'm learning C++, i wrote a small project that has these files:

Log.h
Log.cpp

Render.h
Render.cpp

Tid.h
Tid.cpp

________________________
In TID.h :

#ifndef TID_HPP_INCLUDED
#define TID_HPP_INCLUDED

typedef unsigned char byte;

......
#define EXIT_SUCCESS 0
.....
#define BGI_DRIVER "SVGA64K"
#define BGI_600_480 4
#define SCREEN_WIDTH 600
....
#define LOG_FILE_NAME "log.txt"

#include <graphics.h>
#include <stdlib.h>
#include <conio.h>
#include <dos.h>
#include <mem.h>
#include <stdio.h>

#include "Log.h"
#include "MouseLib.h"
#include "Render.h"

#endif

-----------------------------------
TID.CPP

#include "TiD.h"

int main(void)
{
...........
return EXIT_SUCCESS;
}

___________________
In LOG.h i have:
#ifndef LOG_HPP_INCLUDED
#define LOG_HPP_INCLUDED

void CLog_write(const char *s);


#endif

________________________________
Log.CPP

#include "TID.h"

void CLog_write(const char* s){ ../*write file*/... }


------------------------------------------------------
Render.H
#include "tid.h"

#ifndef RENDER_ENGINE_HPP
#define RENDER_ENGINE_HPP

typedef struct tagBITMAP{
.....} BITMAP;


class CRender
{
public:
CRender();
~CRender();
void fskip(FILE * fp,int);
......
private:
......
}

---------------------------------------------------------
RENDER.CPP

#include "TID.h"

// Initialize graphic mode.
CRender::CRender()
{
/* init BGI driver */
}

void CRender::putImage (const char * filename,int x,int y,int ops)
const
{
FILE *fp;
....
CLog_write("CRender::putImage() : Invalid BMP file");
.....
}
....

--------------------------------------------------------



When i compile in TC++ 3.0 i have error message:
Error LOG.CPP 3: Too many types in declaration.


I think the problem maybe about "include header" but i don't know much
about may files and many header, before i wrote simple programs with
1 file (and one header).

Thank for your help.

Nothing sticks out. See the guidelines for posting code:

http://parashift.com/c++-faq-lite/how-to-post.html#faq-5.8

Post a minimal but *complete* example that we can copy and paste
unchanged into our editors to see the error you get. (Note that we
don't have non-standard headers like graphics.h, dos.h, or conio.h.)

Cheers! --M

That's true, it doesn't really "stick out"...

DO NOT ATTEMPT TO LEARN C++ USING Turbo C++ 3.0!!!

This compiler is more than a dozen years old, and from long before the
C++ language standard. It is an exercise in futility.

If you want to learn C++, get an up to date compiler. There are
several free for download.

Missing semicolon.

You got that rather esoteric error message because the compiler
sees:

class CRender { } int main()

and thinks you are declaring main to return a CRender and an int,
but functions are only allowed to have one return type.

Thanks. I solve that problems.

when compile i have error message:
RENDER.H 14: Declaration syntax error.

I don't know why it happens.

#include <stdio.h>

#ifndef RENDER_ENGINE_HPP
#define RENDER_ENGINE_HPP

typedef struct tagBITMAP
{
unsigned short width;
unsigned short height;
unsigned char pallete[256*3];
unsigned char * data;

Which one is line 14?

See FAQ 5.8.
#include <stdio.h>

#ifndef RENDER_ENGINE_HPP
#define RENDER_ENGINE_HPP

typedef struct tagBITMAP

unsigned short width;

What's a "byte"?
void fskip(FILE * fp,int);
void PutImage (const char * filename,int x,int y,int ops) ;
private:
int m_iGDriver;
int m_iGMode;
int m_iErrorcode;

};

You need to say which line is line 14, and post the exact
code you are compiling. (For example, "byte" in the code
below is undefined, but that can't be line 14).
#include <stdio.h>

#ifndef RENDER_ENGINE_HPP
#define RENDER_ENGINE_HPP

typedef struct tagBITMAP
{
unsigned short width;
unsigned short height;
unsigned char pallete[256*3];
unsigned char * data;
}BITMAP;
Click to expand...

Just a stab in the dark here, but your coding style indicates
you are writing a MS Windows application. MS Windows
header files already define "BITMAP". So if you include
this header after you have included windows.h etc. then
you might get that error.

What happens if you change BITMAP to spoo?
Maybe BITMAP is defined somewhere else.
(All caps are normally reserved for defines BTW)

How about if you remove the typedef for the struct
and do it like c++?

struct tagBitmap{...}

tagBitmap spoo;
....

Then I'm out of ideas. You typically get this
sort of error when a preceding declaration is
not terminated properly, for example, an
included header with a class declaration missing
the ;

i have written this program and this is giving just one error and that is "too many types in declaration".Please help..........

#include<iostream.h>
class invent2
class invent1
{
int code,items;
float price;
public:

{
code=a;
items=b;
price=c;
}
void putdata()
{
cout<<"Code: "<<code<<"\n";
cout<<"Items: "<<items<<"\n";
cout<<"Price: "<<price<<"\n";
}
int getcode(){return code;}
int getitems(){return items;}
float getprice(){return price;}
operator float(){return(items*price);}
/*operator invent2()
{
invent2 temp;
temp.code=code;
temp.value=price*items;
return temp;
}*/
};
class invent2
{
int code;
float value;
