What are the SOLID principles, and why are they important

 The SOLID principles are a set of five design principles in object-oriented programming that help developers create more understandable, flexible, and maintainable software. These principles were introduced by Robert C. Martin, also known as Uncle Bob. They are: Single Responsibility Principle (SRP) Open/Closed Principle (OCP) Liskov Substitution Principle (LSP) Interface Segregation Principle (ISP) Dependency Inversion Principle (DIP) 1. Single Responsibility Principle (SRP) A class should have only one reason to change, meaning it should have only one job or responsibility. Importance: Promotes cohesive functionality. Simplifies debugging and testing. Makes the system more understandable and reduces the risk of changes affecting unrelated functionalities. 2. Open/Closed Principle (OCP) Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification. Importance: Encourages code reuse and flexibility. Reduces the risk of introducing bugs

Solid Principles with Usage Scenario

 The SOLID principles are a set of design principles intended to make software designs more understandable, flexible, and maintainable. Let's break down each principle and provide a scenario where it would be particularly useful: 1. Single Responsibility Principle (SRP) Definition: A class should have only one reason to change, meaning it should only have one job or responsibility. Scenario: Imagine you have a class ReportGenerator that generates reports and also handles the logic for saving the report to a database. If you need to change the database saving logic, you'll have to modify ReportGenerator , even though the report generation logic hasn't changed. To adhere to SRP, you can split this into two classes: ReportGenerator (responsible for generating reports) and ReportSaver (responsible for saving reports). 2. Open/Closed Principle (OCP) Definition: Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification. S
