Which feature of OOP indicates code reusability?

Which of the following provides code reusability?

Which of the following provides a reuse mechanism? Explanation: Inheritance provides a reuse mechanism.

What is reusability in oops?

Inheritance supports the concept of “reusability”, i.e. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. By doing this, we are reusing the fields and methods of the existing class.

Which feature of OOPS derives the class from another class?

Explanation: Inheritance is an important OOPS feature which derives the class from the base class or superclass. This OOPS feature inherits the features of another class in the programs. This mechanism actually inherits the fields and methods of the superclass.

Which among the following feature is not in the general definition of OOPS *?

Platform independent. Explanation: Platform independence is a feature which does not come under the OOPS concepts. This feature depends on the programming language. C++ is an object-oriented programming language which is not a platform-independent language.

What do you mean by reusability?

Capable of being used again or repeatedly.

How code reusability is achieved in oops?

Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or super class or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.

What is the use of code reusability?

Code reuse is the practice of using existing code for a new function or software. But in order to reuse code, that code needs to be high-quality. And that means it should be safe, secure, and reliable.

How code reusability is achieved in Java?

Inheritance lets you extend a class with one or more child classes that inherit the fields and methods of the parent class. It's an excellent way to achieve code reusability. In Java, you need to use the extends keyword to create a child class.

How is reusability supported by inheritance explain with example?

Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents. With inheritance, we can reuse the fields and methods of the existing class. Hence, inheritance facilitates Reusability and is an important concept of OOPs.

Which OOP feature derives all the properties and Behaviour of the one class and used in the another class?

Inheritance is the procedure in which one class inherits the attributes and methods of another class.

Which two features of object-oriented programming are the same?

Encapsulation and Abstraction are the same OOPS concepts. Encapsulation hides the features of the object and binds all the properties inside a single class.

Which is not a feature of OOP in general Definitions * Efficient code code reusability modularity duplicate redundant data?

Which is not feature of OOP in general definitions? Explanation: Duplicate/Redundant data is dependent on programmer and hence can't be guaranteed by OOP. Code reusability is done using inheritance. Modularity is supported by using different code files and classes.

Which among the following is not a use of object?

The objects can't be used to define any member function. Member functions must be defined by the class only.

Which feature support reusability and extensibility of classes?

Feature of Reusability is followed by inheritance so the correct answer is the inheritance.

Which concept allows you to reuse the written code?

Which concept allows you to reuse the written code? Explanation: Inheritance allows you to reuse your already written code by inheriting the properties of written code into other parts of the code, hence allowing you to reuse the already written code.

Which of the following concepts of OOPS means exposing only necessary information?

Data hiding is the concept of oops which means exposing only necessary information to clients. Data hiding is a technique used in object-oriented programming.

Why is reusability important to companies?

Reusability is a major contributor to the development goal of achieving high speed, low cost and quality. Usually, it is better and faster to employ proven off-the-shelf designs rather than specially-crafted designs that might have problems.

What are the 5 OOP concepts?

When completing an object-oriented design, there are five basic concepts to understand: classes/objects, encapsulation/data hiding, inheritance, polymorphism, and interfaces/methods.

How does object-oriented software development achieve and improve reusability?

In object-oriented systems, assessing reusability plays a key role in reducing a cost and improving the quality of the software. Objectoriented programming helps in achieving the concept of reusability through different types of inheritance programs, which further help in developing reusable software modules.

Which feature of OOPS derives the class from another?

Inheritance is an important OOPS feature which derives the class from the base class or superclass. This OOPS feature inherits the features of another class in the programs.

Which is not features of OOP in general definition?

Duplicate/Redundant data.

Which of the following is not a feature of OOP Mcq?

Platform independence is not feature of OOP.

What is object model in OOPS?

An object model is a logical interface, software or system that is modeled through the use of object-oriented techniques. It enables the creation of an architectural software or system model prior to development or programming. An object model is part of the object-oriented programming (OOP) lifecycle.

What is encapsulation in OOP Mcq?

It is a way of combining both data members and member functions, which operate on those data members, into a single unit. We call it a class in OOP generally.

Which of the following is are the characteristics of an object?

An object has identity (each object is a distinct individual). An object has state (it has various properties, which might change). An object has behavior (it can do things and can have things done to it).

Which programming languages are OOP?

Java, Python, C++, Lisp, and Perl are all examples of popular object-oriented programming languages. They support programming using the classes and objects paradigm.

What is reusability in OOP?

Inheritance supports the concept of “reusability”, i.e. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. By doing this, we are reusing the fields and methods of the existing class.

Which of the following features of OOP is not used in following C++ code?

As i and j members are private i.e. they are hidden from outer world therefore we have used the concept of abstraction.

What are the 4 major OOPs concepts?

The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism.

What are the 4 OOPs concepts?

Now, there are four fundamental concepts of Object-oriented programming – Inheritance, Encapsulation, Polymorphism, and Data abstraction.

Is software reusability more OOP?

One of the promises which OOP (Object-Oriented Programming) holds is that it enhances software reusability. Indeed, software components designed in OOP is easier to be reused than those designed in conventional programming.
