In object-oriented programming, when you want to define a method, such as a draw function, that should be accessible to derived classes but not to the outside world, you typically declare it as "protected." This allows the function to be inherited by subclasses while keeping it safe from external access, ensuring that only the intended classes can use or modify it. If you're dealing with polymorphism and need different classes to provide their own implementation of the draw function, declaring it "virtual" in the base class is key. This enables you to call the appropriate draw method for the derived class at runtime, promoting flexible and extensible design in your code.
