Q1Domain Verified
Within the context of "The Complete C# OOP Principles Course 2026", which of the following best exemplifies the principle of polymorphism when designing a system for a graphical user interface (GUI) framework?
C) Creating separate `CircleDrawer` and `SquareDrawer` classes that each contain a `Draw()` method, requiring explicit instantiation of the correct drawer for each shape.
Declaring a base `Shape` class with a virtual `Draw()` method, and then having derived classes like `Circle` and `Square` override this method to implement their specific drawing logi
Employing a factory pattern to create `Shape` objects, where the factory method returns a generic `object` that needs to be cast to the specific shape type before drawing.
Using a `switch` statement to check the type of a `Shape` object and then calling specific drawing methods like `DrawCircle()` or `DrawSquare()`.
Q2Domain Verified
Considering the advanced concepts covered in "The Complete C# OOP Principles Course 2026", what is the primary benefit of using the Strategy pattern to encapsulate interchangeable algorithms within a C# application, beyond simple conditional logic?
It enforces strict compile-time type checking, ensuring that only compatible algorithms can be applied to a given context.
It allows for runtime modification of class inheritance hierarchies, enabling dynamic adaptation of object behavior.
It promotes code reusability by abstracting common behavior into a base class, which can then be inherited by multiple concrete strategies.
It decouples the client code from the specific implementation details of an algorithm, allowing algorithms to be swapped out without altering the client's core logic.
Q3Domain Verified
In the advanced discussions of "The Complete C# OOP Principles Course 2026" regarding SOLID principles, how does the Dependency Inversion Principle (DIP) primarily contribute to building loosely coupled and maintainable C# systems, particularly when dealing with external services?
By promoting the use of concrete implementations in high-level modules, reducing the need for abstraction and simplifying initial development.
By mandating that classes should be responsible for creating their own dependencies, promoting encapsulation and reducing external interference.
By ensuring that high-level modules directly depend on low-level modules, facilitating direct control and immediate feedback.
By requiring that both high-level and low-level modules depend on abstractions, and that abstractions do not depend on details, thus allowing for easier substitution of implementations.
