programming C in Visual C++ express edition.
-
have you tried:
#include "stdio.h"
-
yes i did it doesn't add the header gives out an error message before i run my hello world program
So what is the error message?
-
So what is the error message?
-
Just tells me that there are errors during compilation. and displyas a built-in hello world example result (when you choose that you want to build c++ console it already writes a c++ hello world program using iostream.h)
Those error messages are telling you what's wrong. If you want help, you must tell us what the error messages say.

I need to learn C because I am about to develop microcontroller projects that use C. I got books about C. I might need C++ in the future, but for totally different things. Is it possible to use stdio.h in MS Visual C++? How do I do so? How do I keep command prompt applications from closing the console after they are done playing? If i want to see my "hello world" or some variable number output. Is Keil uVision the only compiler to suit ARM microcontrollers? Maybe I need something like Borland compiler so I can write ARM code and PC code on the same compiler? Thank you.
if you want C, not C++, then make sure your source file has extension .c rather than .cpp For a simple C app, you can delete most if not all pre-generated file content in Visual. A console app will clause automatically when main returns (unless ran from inside Visual Studio). You can change that by ending main on (pseudo-code!):
Console.Write("Hit ENTER to terminate");
Console.ReadKey();There must be dozens of compilers running on PC and targeting ARM. Some vendors offer hundreds of combinations (all kinds of languages, all kinds of targets). Not sure Borland is one of them; personally I don't see an advantage, I've done C for many targets (choosing the best compiler for each of them), and for PC (using Visual Studio). :)

no maybe i should switch to a different compiler visual studio professional is very big too big for my computer

:doh: You know that you will still get these errors with another compiler, since these are compilation errors and they won't magically disappear if you use another compiler.

You need to add the sdk information to your Visual Studio. e.g: add "D:\Program Files\Microsoft SDKs\Windows\v6.0A\bin" to "Executable files", add "D:\Program Files\Microsoft SDKs\Windows\v6.0A\Include" to "Include files", add "D:\Program Files\Microsoft SDKs\Windows\v6.0A\lib" to "Libraray files", ... Please check these settings of Visual Studio on your machine.

Given this and your other comments, maybe you should hold off on the 'microcontroller projects' until you have a better understanding of development. Otherwise, you'll just end up frustrated.

Yes you can use stdio.h - VC++ has been a pretty C89 standard compliant C compiler since about 1997. It's unlikely to grow any C99 features in the short term though. Use CTRL+F5 to run your code - then the console window window won't close when the program exits. It'll just sit there with a "press any key to continue..." message. There are loads of compilers that support ARM. I've used gcc for developing on mobile phones and some of my collegues have used a couple of proprietary compilers as well. Doing a quick google for "ARM C compiler" gave me 8 relevant hits on the first page. Cheers, Ash

I am not talking about microcontrollers right now. I will get to that. Here is the question. So I have Microsoft Visual C++ Express edition and I am struggling to create a C console application. I am not sure how I ADD a stdio.h header and a main source file to accept the C code. I am sure it is possible, it is just that al defaults in VC++ are for C++ and object-oriented programs I won't need for a while. I can create a class. I can create a header file. I can't create a plain code file. I don't know what to type into the header file. Thank you.

From the File menu, click New then Project. In the New Project dialog, select Win32 Console Application. Give the project a name, and verify the Location. No need for a Solution. In the Application Wizard dialog, just accept the defaults. In the Solution Explorer pane on the left, right-click Source Files and select Add then New Item. Add a C++ file, and give it a name. That file should show up in the left pane under Source Files. Double-click it to start editing. Add something like the following to it:
#include <stdio.h>
void main( void )
{
printf("Hello World\n");

Thank you. But when I try to run the empty project it tells me that it cannot find a file path to my project "lesson1\debug\lesson1.exe" (lesson1 is my first project name) this message pops out, nomatter where I create it, the desktop or the default vc++ folder in my documents.

Have you tried Googling for the error number/message?

I did. I had to hit "build solution" before running it. However it doesn't want to compile the #include void main( void ) { printf("Hello World\n"); } The building information in "Output" tells me that there is one error the compiler had to skip somewhere.
