What are the possible consequences of violating SOLID principles in software development?

Violating SOLID principles during development can lead to a number of negative consequences:

• Support and extension complexity: the code becomes tangled, and changes in one part can cause errors in another.
• Poor readability and understanding of the code: other developers find it difficult to understand the logic and structure.
• High coupling of components: changing one class requires modifications in many others.
• Low reusability: the code is hard to reuse due to tight coupling and lack of abstractions.
• Increase in bugs: due to the absence of clear structure and responsibilities.

For example, violating the Single Responsibility Principle results in a class performing too many functions, complicating its testing and modification.
