Thread: Regarding scope

Hi all,

I dug up an old C project of mine that I want to use to apply new principles to in C++. It's a simple text-based game that I can't seem to get working.

Basically, I wrote all the original code in Dev-C++ and have found the Visual C++ 2010 Express Edition to be much better and more likable to use. The problem is, the code won't compile in it. I believe it's a concern with scope, as I'm getting warnings, errors and red lines under things like variable names, functions, etc.

Some errors include:
Undeclared identifier
'close' undefined; assuming extern returning int.
'name' unidentified, depite the fact 'name' is declared as global.

"close" is also red lined and is an unknown function to the compiler despite the fact I have included the correct headers, which are:

Code:

#include<stdio.h>

#include<ctype.h>

#include<stdlib.h>

#include<time.h>

#include<windows.h>

#include<string.h>

I can't understand this. The Dev-C++ setup was thus: write an 'includes' header file and put all my #includes in there, then include this header file in main(). This seemed to allow every source file in the program to have access to anything I required it to have access to, such as <time.h>.

This doesn't work in VC++. Even if I manually include all the header files and necessary includes within each source file, it still won't run my code and some attempts have even told me I've used too many header files.

I was under the impression that C code is the same wherever you go, but apparently not?

Can anyone help me out a little? I'm considering just forgetting this environment and going back to Dev-C++, but I really don't want to.

Thanks for reading.

Thanks for the post, but I'm not after help with C++. As I mentioned, it's an old and forgotten C project I am looking to update with newly learned C++ code as I go, but in its current form it's all C code which I am having trouble compiling in the new development environment.

Unless you were referring to the fact I am using VC++, but I doubt that as the compiler will accept all standard C code.

Thanks.

I'm sorry for the confusion.

There are a few reasons I'm using the C++ compiler.

1. I'm going to be applying C++ code and principles to the project as & when I learn it.

2. The original code was written in a C++ compiler (Dev-C++).

3. Visual C++ contains a C compiler.

So as I said, I don't want help with C++ code as I don't have any yet, it's the compiler errors and warnings I don't understand and just wanted a little advice.

Thanks again.
