What is the importance of abstraction in C++?

Abstraction in C++ allows programmers to focus on high-level functionalities without worrying about low-level details. It simplifies code management and enhances readability.

Can you give me an example of abstraction in C++?

Sure! An example of abstraction is using abstract classes and interfaces. For instance, you can define a base class 'Shape' with a pure virtual function 'draw()'. Derived classes like 'Circle' and 'Square' implement the 'draw()' method, allowing you to work with shapes without knowing their specific implementations.

How does abstraction improve code maintainability?

Abstraction improves maintainability by allowing changes to be made in the implementation of a class without affecting the code that uses it. This separation of interface and implementation makes it easier to update and manage code.

Are there any downsides to using abstraction?

Yes, while abstraction simplifies code, it can also introduce complexity if overused. It may lead to performance overhead and can make debugging more challenging if the abstraction layers are too deep.
