I need the user to be able to run my program with different values *without* recompiling it. I was a C programmer years (and years) ago and vaguely recall being able to do this. I thought I used #defines in my .h file but the changes don't seem to work in my current environment (code::blocks) unless I recompile.
Any ideas?
Thanks.
You can't. Macros (which are created by #define) are a compile-time construct.
What are you trying to achieve? If you want the user to be able to select things at runtime, you could use command-line arguments, environment variables, or configuration files, etc etc etc. But it all depends on what your actual goal is.
You could make the value you want to change something that you read in from the keyboard but other than that I can't think of any way that you can change values in a program without recompiling it.

I currently use some command-line args and also have the user answer a series of questions but I don't like it.
Maybe a config file is what I am thinking of....
Thanks.

You might be thinking of INI files; a type of config file of common use about 15 years ago.
It was used a lot in Windows 95/98 and earlier. It is still used, today, but Windows Registry has almost replaced it, completely.

Well actually nowdays we've almost come full circle it seems. Think ClickOnce etc.
