How does SRP improve maintainability?

SRP improves maintainability by:

• Reducing complexity – Classes are smaller and easier to understand.
• Easier testing – Each class can be tested in isolation.
• Better separation of concerns – Business logic, data access, and infrastructure

code are kept apart.

• Lower risk of bugs – Changes in one responsibility don’t affect others.

Ultimately, it leads to more modular, flexible, and robust code.
