Solution

Object-Oriented Programming (OOP) is a programming paradigm that uses "objects" to design applications and software. These objects are instances of classes, which can hold both data and functions that operate on that data. The key principles of OOP are encapsulation, inheritance, and polymorphism.

  1. Encapsulation: This principle is about hiding the internal details and mechanics of how an object does something. For example, a car is an object which encapsulates the principle of moving, but you don't need to know how the engine works in order to drive it.

  2. Inheritance: This is a way to form new classes using classes that have already been defined. The new classes, known as derived classes, inherit attributes and behavior of the pre-existing classes, which are referred to as base classes.

  3. Polymorphism: This principle allows one interface to be used for a general class of actions. The specific action is determined by the exact nature of the situation. For example, you might have a general class called Shape, and specific shapes like Circle, Square, and Triangle. Each of these shapes would have a method called Area() that would calculate the area for the specific shape.

In contrast, procedural programming is a programming paradigm that uses a linear or top-down approach. It is based on the concept of the procedure call where different procedures are often done in a sequential manner. Procedures, also known as routines, subroutines, or functions, simply contain a series of computational steps to be carried out. Any given procedure might be called at any point during a program's execution, including by other procedures or itself.

The main difference between the two is that while procedural programming uses procedures to operate on data structures, object-oriented programming bundles the two together, so an "object", which is an instance of a class, operates on its "own" data structure.
