2.4 Creating a C++ Back-End Component

Now that the button is created in the QML file, add functionality to them so that the button can produce some results when clicked. To achieve this, write a C++ application that handles the back-end components of the project.

This is a common approach in Qt development, where a user uses QML for the front-end (user interface) and C++ for the back-end (business logic). By separating the front-end and back-end, a user keeps code organized and maintainable.
