Which feature of OOP indicates code reusability? explain: heritage Indicates code reusability.

Which C++ OOPS feature is relevant for reusability?

Q) Which C++ oops feature is related to reusability? Inherited features The concept of code reusability because in inheritance, a class can inherit the properties and functionality of an existing well-written class.

Which concept provides the concept of reusability?

Reusability: heritage Supports the concept of « reusability », i.e. when we want to create a new class and we already have a class that contains some code 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.

Why is reusability important in OOP?

Abstract.In object-oriented systems, assessing reusability Plays a key role in reducing costs and improving software quality. Object-oriented programming facilitates the realization of the concept of reusability through different types of inheritance procedures, which further facilitates the development of reusable software modules.

What is the concept of reusability?

In computer science and software engineering, reusability is Use existing assets in some form during software product development; These assets are the products and by-products of the software development life cycle, including code, software components, test suites, designs, and documentation.

Is modularity implemented in oops?

Modular is Intrinsically linked to packaging. Modularity can be visualized as a way of mapping encapsulated abstractions to real physical modules with high cohesion within modules and low interaction or coupling between them.

What is the smallest function in oops?

Answer: The 4 basic characteristics are Inheritance, polymorphism, encapsulation and abstraction. In addition, one must use objects, the second is message passing, and the last is dynamic binding. Explanation: The interaction between two objects is called the message passing feature. Data transfer is not a feature of OOP.

What is the difference between inheritance and reusability?

1. Inheritance is a type of creating a new class (derived class) that inherits the characteristics of an existing class (base class).However polymorphism can be defined in many ways.

Which bad code is accepted to reuse code?

Which concept allows you to reuse the code you write? explain: heritage Allows you to reuse code that has already been written by allowing you to reuse the code you have written by inheriting the properties of the written code into other parts of the code.

What does polymorphism in Oops mean?

Polymorphism is the ability of any data to be processed in more than one form.The word itself means poly means many, morphism means type. . . The most common use of polymorphism in object-oriented programming occurs when a parent class reference is used to refer to a child class object.

What does polymorphism in Oops mean in C++?

Polymorphism in C++ means, The same entity (function or object) behaves differently in different scenarios. Consider this example: The « + » operator in C++ can perform two specific functions in two different situations, namely when the « + » operator is used on numbers, it performs addition.

Can the main() function be made private?

Can the main() function be made private? Explanation: The reason given in option « No, because main function is user defined » is wrong.The right reason why the main function should not be private is It should be accessible throughout the program. This makes the program flexible.

Which OOPS concept is used as a reuse mechanism?

explain: heritage is a feature of OOPS that allows users of OOPS to reuse code that has already been written. This OOPS feature inherits the features of another class in the program. This mechanism actually inherits the fields and methods of the superclass.

Which language does not support all 4 types of inheritance?

Which language doesn’t support all 4 inheritance types? explain: Java All 4 types of inheritance are not supported. It does not support multiple inheritance.

Which of the following is true about encapsulation?

Which of the following is possible when using encapsulation? explain: Change the data type of a data member without changing any other code. All members using the data can continue in the same way without any modification. Member functions can never change the data type of data members of the same class.

What are the different types of inheritance?

The different types of inheritance are:

• Single inheritance.
• Multiple inheritance.
• Multilevel inheritance.
• Hierarchical inheritance.
• Mixed inheritance.

What is example inheritance?

Inheritance is a mechanism in which one class acquires properties of another class. E.g, Children inherit characteristics of parents. Through inheritance, we can reuse fields and methods of existing classes. Therefore, inheritance promotes reusability and is an important concept of OOP.

Does polymorphism require inheritance?

Flexible programs focus on polymorphism rather than inheritance. Some languages ​​focus on static type checking (c++, java, c#), which links concepts and reduces polymorphism opportunities.

Which of the following is the smallest functionality implemented in OOP?

Which of the following means implementing the least amount of functionality in OOP? heritage. abstract. package.

Which definition best describes an object?

Which definition best describes an object? explain: An object is an instance of its class. It can be declared the same way you declare a variable, the only thing is that you have to use the class name as the data type. …objects can also be passed by value.

What is abstraction in OOP?

Abstraction is the concept of object-oriented programming Only « show » essential properties and « hide » unnecessary information. The main purpose of abstraction is to hide unnecessary details from the user. …it is one of the most important concepts of OOP.

What is modularity in oops?

Modular is The process of decomposing a problem (program) into a set of modules This reduces the overall complexity of the problem. Booch defines modularity as: « Modularity is the property of a system that has been decomposed into a set of cohesive and loosely coupled modules. »

Why do we need modularity?

modular Lets you build complex systems composed of smaller parts that can be independently managed and maintained. Fixes to parts of the code do not necessarily affect the entire system. …this allows your software system to extend functionality without becoming brittle and burdening developers.

What is a modular example?

Modularity is the property that describes the replaceability of system components or modules. … modules can be removed, replaced or upgraded without affecting other components. E.g, Most desktop computers are modular as they have parts that are easy to remove and upgrade.

Can two classes inherit from each other?

multiple inheritance Is a feature of C++, a class can inherit from multiple classes. Constructors of inherited classes are called in the order in which they were inherited.
