The SOLID principles are a set of five design principles in object-oriented programming (OOP) and software design that help make software systems more understandable, flexible, and maintainable. They were introduced by Robert C. Martin (Uncle Bob) in the early 2000s and have since become fundamental guidelines for developers aiming to write high-quality, scalable code.

Overview of SOLID Principles:

[S] Single Responsibility Principle (SRP):

  • A class should have only one reason to change, meaning it should have only one job or responsibility.
  • Benefits: Enhances maintainability by ensuring that changes to a single responsibility affect only one class, reducing the risk of unintended side effects.

[O] Open/Closed Principle (OCP):

  • Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification.
  • Benefits: Promotes code reuse and scalability by allowing new functionality to be added through extension rather than altering existing code, thus minimizing the risk of introducing bugs in already tested code.

[L] Liskov Substitution Principle (LSP):

  • Objects of a superclass should be replaceable with objects of its subclasses without affecting the…
