how to avoid writing main() too many times in C?

Let say I have 5 small 开发者_C百科piece of codes in C. Every time I want to test each piece of code, I have to repeat this process:

#include <stdio.h>
int main()
{
   // code piece go into here
   return 0;
}

Is there way that I don't have to do this 5 times? I'm using Code::Blocks, that means I have to create 5 different projects, which I believe not necessary because each piece of code is small.

Is this really so hard? Every program you run needs a main function, and the text you've pasted there isn't very long. Also, people expect to see a main function in C/C++ programs. If you template this out somehow, you're just going to make your code confusing.

If the issue is that you have to make a project for every test you want to build, then I would guess you are not using your IDE correctly. Is there not a multi-target project type that lets you have multiple test programs without all the extra project files? If there is not, then perhaps you should be using a different IDE.

Use a good editor with code templates. Most feature-full editors (Emacs, vi, Scite, Textmate, or even MSVC if that's your cup of tea) have some support for them. This way, writing this boring template every time will take only a fraction of the second.

Would template files or copying and pasting be too difficult for some reason?
