OCP
The OCP is another fundamental principle in software design. It emphasizes that software entities, such as classes and modules, should be open for extension but closed for modification. What does that mean? It means that once a software entity is defined and implemented, it should not be changed to add new functionality. Instead, the entity should be extended through inheritance or interfaces to accommodate new requirements and behaviors.
When thinking about this principle and if you have some experience writing code for non-trivial programs, you can see how it makes sense, since modifying an entity introduces a risk of breaking some other part of the code base relying on it.
The OCP provides a robust foundation for building flexible and maintainable software systems. It allows developers to introduce new features or behaviors without altering the existing code base. By adhering to the OCP, you can minimize the risk of introducing bugs or unintended side effects when making...
