Why is OOPS so popular?
OOP become a popular since it provide a better programming style, you don’t need to write code which you really need to run anytime you need (such as in structured programming and assembler), you just make a class of object and you may call/instantiate the class and use it from any part of your application, it is …
Why is OOPS needed?
Object-oriented programming is ultimately about taking a huge problem and breaking it down to solvable chunks. For each mini-problem, you write a class that does what you require. And then — best of all — you can reuse those classes, which makes it even quicker to solve the next problem.
Why OOPs is important?
Benefits of OOP OOP language allows to break the program into the bit-sized problems that can be solved easily (one object at a time). The new technology promises greater programmer productivity, better quality of software and lesser maintenance cost. OOP systems can be easily upgraded from small to large systems.
Why do we use OOPs?
Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc. in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.

What are the limitations of OOP?
List of OOP disadvantages:
- Size: OO programs are much larger than other programs.
- Effort: OO programs require a lot of work to create.
- Speed: OO programs are slower than other programs, partially because of their size.
What are the main pillars of Oops?
What is abstraction in OOPs?
Abstraction is the concept of object-oriented programming that “shows” only essential attributes and “hides” unnecessary information. The main purpose of abstraction is hiding the unnecessary details from the users.
