bryyyleeee/TrainBrain — reverse-engineered prompt

Build me a working version of this TrainBrain C project so I can clone it, compile it, and run it on both Linux and Windows without guessing what to do.

The repo is pretty bare right now, so focus on making it usable and easy to understand. Set up the Linux and Windows versions cleanly, add clear compile and run instructions, and make sure any database connection details are handled safely through a config file or environment variables instead of hard coded secrets. If the program needs a database, include simple setup notes and an example credentials file that does not contain real passwords.

I want the end result to feel like a small complete project, not just loose code. Add sensible error messages, basic input validation, and a README that explains what TrainBrain does, how to build it, how to run it, and how to troubleshoot common problems. Look up current docs online if you need to.
