What is the role of controllers in MVC applications?

In MVC applications, controllers act as intermediaries between the model and the view. They handle user input, manipulate data, and update the view accordingly.

Can you give me an example of how a controller works?

Sure! For instance, in a web app, when a user submits a form, the controller processes the input, updates the model, and then selects a view to display the results.

How do controllers interact with models and views?

Controllers receive input from views, call the appropriate model methods to retrieve or update data, and then return the updated view to the user.

What are some best practices for writing controllers?

Best practices include keeping controllers thin, using RESTful conventions, and ensuring they handle errors gracefully.
