Open/Closed Principle
The Open/Closed Principle is a fundamental concept in software design that states that software entities, such as classes and modules, should be open for extension but closed for modification. This means that you can add new functionality to a system without changing existing code, which helps to reduce the risk of introducing bugs and makes the system more maintainable.
By adhering to the Open/Closed Principle, developers can create more flexible and scalable applications. This principle encourages the use of interfaces and abstract classes, allowing new features to be added through inheritance or composition, rather than altering existing code directly. This approach promotes better software architecture and enhances code reusability.
