A class is used in object-oriented programming to describe one or more objects . It serves as a template for creating, or instantiating, specific objects within a program. While each object is created from a single class, one class can be used to instantiate multiple objects.
Read moreWhat is called a class?
In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables.
Read moreWhat is class explain with example in Java?
Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a “blueprint” for creating objects .

C++ Aggregation (HAS-A Relationship) In C++, aggregation is a process in which one class defines another class as any entity reference . It is another way to reuse the class. It is a form of association that represents HAS-A relationship.
Read moreWhat is aggregation and how does it work give an example?
An aggregate object is one which contains other objects . For example, an Airplane class would contain Engine, Wing, Tail, Crew objects. Sometimes the class aggregation corresponds to physical containment in the model (like the airplane). But sometimes it is more abstract (e.g. Club and Members).
Read moreHow does aggregation work in OOP?
Definition of Aggregation in OOPS. Aggregation in OOPS is defined as a relation that exists between two or more two objects which individually have their own individual life cycle along with the ownership . Aggregation in OOPS constitutes 2 words (aggregation and OOPS).
Read moreWhat are the advantages of using a class in C++?
Classes support a powerful programming model by encapsulating related functionality into objects . The benefit of organized code is especially important for maintenance, where changes or enhancements can be limited to the objects that are affected by the change. Classes enhance code reuse.
