Questions related to programming languages and OOPs concepts.

• Java and C++ are both object-oriented languages, but C++ also supports procedural programming.

• Procedure-oriented languages focus on procedures or functions, while object-oriented languages focus on objects.

• Python is an object-oriented language, but it also supports procedural programming.

• OOPs concepts include encapsulation, inheritance, polymorphism, and abstraction.

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• Class is a blueprint for creating objects. It defines the properties and behaviors of objects.

• Inheritance allows a class to inherit properties and methods from another class. It promotes code reusability.

• Function is a block of code that performs a specific task. It can be called multiple times.
