OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Select one: True FalseMap each of the keywords on the left to the statement that describes it the best. Inheritance Class Object Polymophism Instance variable [Choose ] ✓ It is any variable that does not represent a living being. It allows properties and functions to be passed to another object when an object is deleted. It represents a blue print of an object. It is like a global variable that can be accessed in all functions of a program. It is a category to organize variables and objects in groups. It is an instance of a class. It is a programming command with a special meaning. Classes can acquire properties and functions from other classes. It is a property inside that class that exists throughout the lifetime of an object. It is used to define the relationship between classes. It is a variable of a primitive type. It is a variable that can store values of multiple types. It allows a variable of a super class type to be assigned an instance of a subclass type. It is used to describe that a class…

O A. inheritance B. composition O C. association O D. aggregation O E. polymorphismInheritance is an OOP concept such that a class can be defined in different ways, such as either being typecasted to itself (as a subclass) or any of its superclasses. True FalseComputer Science Object Oriented Analysis and Design. Look at the problem described below and describe how you would break it into objects, consider ways to use inheritance and composition. Describe for me how those objects make a system of objects that solves the problem. You may use UML or just write out a list of classes describing their properties and interface. You should also include a short description of how those objects work together.
