The question covers topics like C vs C++, OOPS concept, virtual mechanism, multi-threading, and security products.

• C is a procedural programming language, while C++ is an extension of C with added features like classes and objects.

• OOPS (Object-Oriented Programming) is a programming paradigm that focuses on objects and their interactions.

• Virtual mechanism allows a derived class to override the implementation of a method defined in the base class.

• Multi-threading is the ability o...read more

OOPS (Object-Oriented Programming) is a programming paradigm that uses objects to represent real-world entities and their interactions.

• OOPS focuses on the concept of objects, which are instances of classes.

• It emphasizes encapsulation, inheritance, and polymorphism.

• Encapsulation ensures that data and methods are bundled together within an object.

• Inheritance allows classes to inherit properties and behaviors from other classes.

• Polymorphism enables objects of different classes t...read more
