That enables the user to implement more complex logic on top of the provided abstraction without understanding or even thinking about all the hidden complexity. Encapsulation and abstraction are meant to hide/group data into one element. d) Data hiding An object can be viewed as a real-world entity which has attributes and behaviour. It can be best explained with an example with a comparison to C language; in C language there was one limitation that we can not use the already used function name, but C++ provides us a new feature of Polymorphism, by which we can use the same function name again and again with different signatures. Which Oops is accepted to reuse the code? These classes are further used for creating instances of the objects. d) Function Overriding Answer: b Explanation: Inheritance indicates the code reusability.

Object-oriented programming (OOP) is known as the most common programming paradigm. With an object of a class, we can access the data members and member functions that can be accessed (as per the private, public, protected accessibility scope). Simply classes consequently define the type of their instances. Classes are commonly used to indicate large groupings with similar characteristics. a) True A class is Blueprint of an object which describes/ shows all the functions and data that are provided by an object of a specific class.

An object is referred to as a data field that has unique attributes and behavior. Reusability in OOP is achieved by using C++ features that allow you to extend or reuse parent, super class, or base class properties in a subclass, as well as adding additional features or data members to the subclass, child class, or derived class. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. 2004. 5. for Reusability .cpp file is known as a source-code file Header files Separate files in which class definitions are placed Allow compiler to recognize the classes when used elsewhere Generally have .h filename extensions Driver files Program used to test software (such as Encapsulation is achieved when each object keeps its state private, inside a class. The Object oriented programming makes it easier to the programmers to design and organize software programs. Classes are organized into hierarchies, and inheritance enables one classs structure and functions to be transferred down the hierarchy. Answer: (c). 2.

Because an object can only be associated with data in predefined classes or templates, the object can only "know" about the data it needs to know about. d) Inheritance is a feature of OOP that allows a class to inherit the properties and methods of another class. It is based on the concepts of objects and classes, which bundle together properties (data members) and behaviours (member methods). Thus, you may use multiple prototype object templates to form a prototype chain. OOP features include the following: Encapsulation: This makes the program structure easier to manage . Following are the features of Inheritance described.

Object-oriented programming (OOP) is a software programming model constructed around objects. For example, objects may override common parent behaviors with particular child behaviors through inheritance. Polymorphism. Because a polymorphic object can operate on a variety of values and types, it can also be used in a variety of programs, sometimes with little or no change by the programmer.
