The pros of using Object-Oriented Programming  Languages are as follows:

• Object-Oriented Programming  Languages follow a bottom-up approach which helps programmers in simulating the real world and its entities.
• It makes code re-usability possible.
• Using abstraction, the user is not exposed to superfluous data.
• Object-Oriented Programming  Languages requires designers to go through a LENGTHY and thorough design phase, which yields a better design with fewer faults.
• Object-Oriented Programming  Languages break down a large problem into smaller pieces.
• Programmers are able to achieve their objectives more quickly via Object-Oriented Programming  Languages.
• The usage of Object-Oriented Programming Languages reduces the amount of complexity of code written by programmers.
• Code may be EASILY redesigned and EXTENDED without affecting other features.

The cons of using Object-Oriented Programming  Languages are as follows:

• It is necessary to do a lot of PLANNING in order to use these languages.
• There is a tendency for classes to be overly generalized in Object-Oriented Programming Languages.
• These are not SUITABLE for small problems as they lead to over-complication.
• In certain instances, programs written in Object-Oriented Programming Languages can consume a lot of memory which is obviously unwanted.
