Class and Object in C++:


C++ is an object-oriented programming (OOP) language where the concepts of classes and objects are central. The main goal of OOP is to use programming in a natural and organized way to solve real-world problems.

1. What is a Class?
A class is a blueprint or template used for creating objects. It includes data (data members) and the functions that operate on that data (member functions). A class can be thought of as a "user-defined data type."
Features of a Class: Encapsulation, Data Abstraction, Inheritance, and Polymorphism.

2. What is an Object?
An object is an instance of a class. Objects are the real entities through which we use the properties and functions of a class. When an object is created, memory is allocated for it.

Relationship between Class and Object:
A class is the blueprint that defines objects. An object is a real instance of a class. For example, if "Car" is a class, then "my car" would be an object.

Advantages of Class and Object:
Code reusability, data security (by making members private), simplifying complexity, abstraction, and inheritance.
