What practices should be followed to write clean and maintainable software?

To write clean and maintainable software, it is recommended to follow these practices:

• Code readability: use understandable variable and function names, avoid unnecessary complexity.
• Modularity: break down the code into small, independent, and reusable components.
• Documentation: write comments where the logic may not be obvious.
• Follow coding standards: use a consistent code style.
• Test coverage: write automated tests to verify functionality.
• Avoid code duplication: apply the DRY (Don't Repeat Yourself) principles.
• Refactoring: regularly improve the code structure without changing its behavior.

These practices help make the code understandable for other developers and facilitate support and project development.
