/*Prints a charter and some numbers */
#include <stdio.h>
main()

Get a book published after 1989? :D Visit the FAQ?
FAQ > What's the difference between... > main() / void main() / int main() / int main(void) / int main(int argc, char *argv[])

Compile "C" code with a C++ compiler?

You can compile your code as C in VC++ 2005. In your project properties go to C/C++ -> Advanced -> Compile As

well im using a c++ compiler, will that not work on c programming?

I would say that right now it is highly recommended that you avoid extra unnecessary confusion.

thank you, now i have another problem.

It all works now, but it goes so quickly i cant tell if what im programming is correct.

how can i stop the compiler from closing the console?

FAQ > How do I... (Level 1) > Stop my Windows Console from disappearing everytime I run my program?

Edit: Beaten. And yeah, it's been answered "eleventy billion times". Though I personally like my programs executing in a blink of an eye. (Run it from the console!)

By reading the FAQ. Why do people keep asking this question? We've answered it eleventy billion times. Someone needs to sticky the answer.
Read this for some ideas: http://faq.cprogramming.com/cgi-bin/...&id=1043284385
Which will refer you to here:

Even 4chan knows this one: http://dis.4chan.org/read.php/prog/1152142735/ :D

I don't like mine executing in the blink of an eye...but of course most of my programs are Win32 ones so if it executes in the blink of an eye there's a problem with the window or the message loop ;). Lol from the 4chan link I found a quote I like: "Ah well. At least it's good to see that you haven't started with the java faggotry." Lol, I thought I'd share that with you guys.

put an int before main

If you want to write C code I highly recommand to do the simple thing JaWiB posted.

Of course, we'd still tell him to use a proper declaration for main. ;)

Compile As is bad. It overrides the settings when they probably shouldn't be overridden. Just give the file a .c ending (instead of .cxx, .cpp, .cc, or anything like that) and the environment will compile it as C by default.
