Header Files HELP?!?!?!

Why won't my code recognize a header file? It won't compile for some reason? Please Help. The code is written right from the C++ for Dummies book.

main.cpp

#include <iostream>
#include <stdlib.h>
#include "safestuff.h"
using namespace std;
int main(int argc, char *argv[])
{
cout << "Surprise, surprise!" << endl;
cout << "The combination is (once again)" << endl;
cout << SafeCracker(12) << endl;

system("PAUSE");
return 0;
}

safestuff.h

#include <safestuff.h>
string SafeCracker(int SafeID);

safestuff.cpp

#include <string>
#include <safestuff.h>
string SafeCracker(int SafeID) {
return "13-26-16";
}

At least the line I have higlighted should not be there...no need to include the file you are all ready working on. An other good idea is to use guards, so the header file won't be included twice. That might be a problem here too, since you are including it two times. Change the whole code in safestuff.h to this:

Code:

---

#ifndef _SAFESTUFF_H
#define _SAFESTUFF_H

string SafeCracker(int SafeID);

#endif

---

In safestuff.cpp, you have the wrong delimiters for safestuff.h's name.

What should the delimeters be? My compiler won't get past the main.cpp. Here is the error report. Any Ideas??

Line 3 | File BLAH BLAH | In file included from main.cpp

What compiler do you use?

It should be

#include "safestuff.h"

I tried that and it still doesn't work.

How do I know what compiler I'm using? In the compiler options it just says "Default compiler".

What IDE, then?

DEV-C++ 4.9.9.0

Ok, now tell me what really was there instead of the BLAH BLAH.

c:\misc\CPP\FirstProject\main.cpp

Maybe this will help. I got it by typing in "cl /?" on the command prompt.

Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8804 for 80x86

No, Dev-C++ uses GCC, not MSC.

I don't believe that was the whole error message, though.

Here is everything I get after I compile (or try to compile).

Go to the tab "compile log" and tell me what it says there.

You have a syntax error inside the header. The line3 thing only shows from where the header with the error was included.

Here is what my header file looks like. What is the syntax error?

Code:

---

#ifndef _SAFESTUFF_H
#define _SAFESTUFF_H

string SafeCracker(int SafeID);

#endif

---

Code:

---

#ifndef _SAFESTUFF_H
#define _SAFESTUFF_H

#include <string>

std::string SafeCracker(int SafeID);

#endif

---

So realy all I had to do was include:

using namespace std;

in all the files. What a PIMA! I wish the book would say that somewhere!!!! Thanks for all your help!!
