Build me a simple C++ hello world program for a college seminar demo.

I just want a clean, working example that compiles and runs without any fuss, with the output showing a friendly greeting on the console. Keep it easy to read and beginner friendly, since this is for a class presentation. If it helps, make the code a little more polished than the most basic version, maybe with a short comment explaining what it does.

If there’s already a starter file, just use that and make sure it works properly. Keep the project very small and simple, and only include what’s needed to run the example. If you need to check anything, look up current docs online first.
