What happens if a class has multiple responsibilities?

If a class has multiple responsibilities:

• It becomes tightly coupled and harder to change without affecting other parts.
• Changes are more error-prone and often introduce bugs.
• Testing becomes harder since the class relies on multiple behaviors.
• Code reusability and readability suffer due to mixed concerns.
• You violate SRP, which makes code harder to maintain in the long run.
