What Grouping objects along with their attributes and methods into a class is called?
Composition.
Difference between composition and inheritance?
The 'is a' relationship is expressed with inheritance and 'has a' relationship is expressed with composition. Both inheritance and composition allow you to place sub-objects inside your new class. Two of the main techniques for code reuse are class inheritance and object composition. Inheritance [ is a ] Vs Composition [ has a ] Building Bathroom House class Building{ ....... } class House extends Building{ ......... } is a [House is a Building] class House { Bathroom room = new Bathroom() ; .... public void getTotMirrors(){ room.getNoMirrors(); .... } } is a has a [House has a Bathroom] has a Inheritance is uni-directional. For example House is a Building. But Building is not a House. Inheritance uses extends key word. Composition: is used when House has a Bathroom. It is incorrect to say House is a Java - Fundamentals 19 Bathroom. Composition simply means using instance variables that refer to other objects. The class House will have an instance variable, which refers to a Bathroom object.

What is meant by instancing a class?
The class can be considered a template to create objects. When you create an object, you create it on the basis of the specified class - the object is an instance of the class, and the act of creating the object is also known as "instantiating" the class.
Explain term composition with example in c plus plus?
Composition relates to the way in which complex objects can be constructed from smaller, simpler objects. We refer to this as object composition. While simple objects typically contain one or more embedded primitive member attributes, such as int, char, float and so on, composite objects typically embed other objects (often in addition to other primitive attributes), and each of those objects may themselves be composite or they may be simple. This allows highly complex object models to be constructed such that each object within a composition is self-contained and ultimately operates no differently to how it would operate if it were a standalone object. The composite object effectively acts as an object coordinator, calling specific methods upon the simpler objects as required. In other words, the actual workload is delegated to the object or objects that are actually responsible for that workload, and they themselves may delegate to simpler objects, and they to theirs. The composite object's only real workload is in processing any relevant results of those delegations. In other words, a simple function call through a member method of the composite object can produce a cascade of member methods within the embedded objects, each of which works completely independently, but the results of which can be combined by the containing object in order to produce highly complex behaviour. By way of an example, a motor car is built up from thousands of individual but ultimately simple components, such as nuts and bolts, switches, cogs, levers, wheels and so on. Some of those simple objects are combined to produce more complex objects, such as an engine, a transmission unit, a steering mechanism, door locks, and so, on. Ultimately, they all combine to produce a car. But no matter how complex a composite object is, the behaviour of their embedded objects does not change: a nut and bolt is still a nut and bolt whether it is holding a door hinge onto a chassis, or a suspension strut to a wheel hub. In other words, the job of physically holding one component to another is delegated to the nut and bolt, but is coordinated according to the object that embeds the nut and bolt, while that object is coordinated and delegated to by the object that contains it, and so on.

Why was 2060 chiron famous?
It was the first known member of a new class of objects known as centaurs.
Class is a factory of objects?
As per the definition of a class it generally defines the features and functions of an object created from it and hence it is known as the factory of objects. intiated by computerscienceexpertise.com

How the objects in a photograph are positioned and presented is known as?
The way objects in a photograph are positioned and presented is known as composition. Composition involves arranging elements within the frame to create balance, harmony, and visual interest. Key aspects of composition include framing, the rule of thirds, leading lines, and the use of space, all of which contribute to the overall impact of the image. Effective composition helps convey the photographer's intended message and engages the viewer.

What is the simply meaning of object oriented?
The short explanation is that it is computer programming that involves classes and objects. A class is a template to create objects; it can also be considered as a data type. Classes allow you to create new data types; for example, you could create a class to handle dates, points in 3D space, etc. Functions, instead of being independent, are associated with a class (and therefore with objects based on the class); such functions are known as "methods". The objects, of course, also need to store data; variables at the class/object level are known as "fields".
What Are blueprints for creating objects.?
Blueprints, also known as classes, serve as templates for creating objects in object-oriented programming. They define the properties and behaviors that objects of that class will have, allowing for consistency and reusability in code. By creating instances of a class (objects), we can leverage the defined blueprint to work with data and functionality in a structured manner.
What are the nouns in this sentence. After this first lesson the class learned about composition?

What is an array of class objects.how the array of class of class objects is defined in c plus plus?
An array of class objects is just a set of class objects arranged linearly in memory. It is no different than an array of elementary objects. You define it the same way. class myClass { ... }; myClass arrayOfMyClass[100]; // creates 100 objects and fires the constructor 100 times
