1.More complex at the start

* Harder to learn than procedural programming.Encapsulation (data protection)

* Methods control how data is accessed or modified.Reusability

* You can reuse classes and methods in different programs.* Requires understanding concepts like classes, objects, and methods.Can be slower

* OOP programs may use more memory and processing due to extra structure.Over-engineering risk

* For simple programs, OOP can be unnecessary and make things more complicated.* Prevents misuse (like passing a bank balance into a sine function).Cons
