programming C in Visual C++ express edition.
-
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.
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

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.

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.

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.

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.
