How Open Closed Principle can also be achieved in many other ways?
The Open-Closed Principle (OCP) states that software entities (classes, modules, methods, etc.) The Open-Closed Principle can also be achieved in many other ways, including through the use of inheritance or through compositional design patterns like the Strategy pattern.
Is inheritance Open Closed principle?
In object-oriented programming, the open–closed principle states “software entities (classes, modules, functions, etc.) Both ways use generalizations (for instance, inheritance or delegate functions) to resolve the apparent dilemma, but the goals, techniques, and results are different. …

When does a program need to be open or closed?
SHOULD BE OPEN FOR EXTENSION, BUT CLOSED FOR MODIFICATION. When a single change to a program results in a cascade of changes to dependent modules, that program exhibits the undesirable attributes that we have come to associate with “bad” design. The program becomes fragile, rigid, unpredictable and unreusable.
