Can you describe how the components of the model, view, and controller in the MVC architecture interact with each other?

In MVC (Model-View-Controller) architecture, components interact as follows:

  • Model: responsible for data and business logic. It stores the application's state and notifies the controller or view of changes.

  • View: displays data to the user. It receives information from the model and updates when changes occur.

  • Controller: accepts user input, processes it, modifies the model, and determines which view to display.

Interaction example:

  1. The user interacts with the interface (View), for example, clicking a button.
  2. The controller receives the event, processes it, possibly changing data in the model.
  3. The model updates its state and notifies the View of changes.
  4. The View updates the data display.

In C#, it might look like this:

// Model
public class Product {
    public string Name { get; set; }
}

// Controller
public class ProductController {
    private Product model;
    private ProductView view;

    public ProductController(Product model, ProductView view) {
        this.model = model;
        this.view = view;
    }

    public void SetProductName(string name) {
        model.Name = name;
        view.Update(model);
    }
}

// View
public class ProductView {
    public void Update(Product model) {
        Console.WriteLine("Product name: " + model.Name);
    }
}

Thus, MVC separates responsibilities, making it easier to maintain and develop the application.
