What is polymorphism in object oriented programming Mcq?

Explanation: In OOPs, Polymorphism is the concept of allowing a user to override functions either by changing the types or number of parameters passed.

What is the polymorphism in object-oriented?

Polymorphism is one of the core concepts of object-oriented programming (OOP) and describes situations in which something occurs in several different forms. In computer science, it describes the concept that you can access objects of different types through the same interface.

What is an object in object-oriented programming Mcq?

Answer: b. Object. Explanation: Object is a technique which can be viewed as an abstraction of the combination of data and code. This OOPS concept uses the class data members and their functioning as the data abstraction. Code abstraction is used as the object of an inbuilt class.

What is polymorphism in OOP give example?

Polymorphism is one of the OOPs feature that allows us to perform a single action in different ways. For example, lets say we have a class Animal that has a method sound() . Since this is a generic class so we can't give it a implementation like: Roar, Meow, Oink etc.

Which function best describes the concept of polymorphism in programming languages Mcq?

Right Answer is:

Only those functions are used to achieve the polymorphism, which is declared as 'virtual'. These functions let the OOPS programs decide at runtime which function is to be called by the pointer.

MCQs-C++ Polymorphism|Key points to remember|Questionnaire

What is polymorphism and types of polymorphism?

Polymorphism is the ability to process objects differently on the basis of their class and data types. There are two types of polymorphism in Java: compile time polymorphism and run time polymorphism in java. This java polymorphism is also referred to as static polymorphisms and dynamic polymorphisms.

Which type of function is used for polymorphism?

Compile time polymorphism: This type of polymorphism is achieved by function overloading or operator overloading. Function Overloading: When there are multiple functions with same name but different parameters then these functions are said to be overloaded.

What is polymorphism in programming?

“In programming languages and type theory, polymorphism is the provision of a single interface to entities of different types, or the use of a single symbol to represent multiple different types.” Polymorphism is essential to object-oriented programming (OOP). Objects are defined as classes.

What is meant polymorphism?

Definition of polymorphism

: the quality or state of existing in or assuming different forms: such as. a(1) : existence of a species in several forms independent of the variations of sex. (2) : existence of a gene in several allelic forms also : a variation in a specific DNA sequence.

What is polymorphism simple?

In object-oriented programming, polymorphism (from the Greek meaning "having multiple forms") is the characteristic of being able to assign a different meaning or usage to something in different contexts - specifically, to allow an entity such as a variable, a function, or an object to have more than one form.

What is an object Mcq?

An object is instance of its class. It can be declared in the same way that a variable is declared, only thing is you have to use class name as the data type.

What is an abstraction in OOP Mcq?

Explanation: Abstraction is hiding the complex code. For example, we directly use cout object in C++ but we don't know how is it actually implemented. Encapsulation is data binding, as in, we try to combine a similar type of data and functions together.

What are the main features of OOPs Mcq?

The 4 basic features are inheritance, polymorphism, encapsulation and abstraction.

What is polymorphism in OOPs C++?

Polymorphism is an important concept of object-oriented programming. It simply means more than one form. That is, the same entity (function or operator) behaves differently in different scenarios. For example, The + operator in C++ is used to perform two specific functions.

Why is polymorphism used?

Polymorphism allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have multiple implementations. The word “poly” means many and “morphs” means forms, So it means many forms.

What is polymorphism Wikipedia?

In biology, polymorphism is the occurrence of two or more clearly different forms or phenotypes in a population of a species. Different types of polymorphism have been identified and are listed separately.

How many types of polymorphism are there?

Polymorphism means "many forms" and is the opposite of uniform. In Object-Oriented programming languages there are three types of polymorphism: subtype polymorphism, parametric polymorphism, and ad-hoc polymorphism.

What are the 4 types of polymorphism?

The Ad-Hoc polymorphism is called as overloading. This allows function with same name to act in different manner for different types.

Which of the following explains polymorphism Mcq?

Which of the following explains Polymorphism? Explanation: Polymorphism means overriding the same function by changing types or number of arguments.

What is the advantage of runtime polymorphism Mcq?

The main advantage of Runtime Polymorphism is the ability of the class to offer the specification of its own to another inherited method. This transfer of implementation of one method to another method is possible without changing or modifying the codes of the parent class object.

What is meant by encapsulation in OOPs?

What does encapsulation mean: In object-oriented computer programming (OOP) languages, the notion of encapsulation (or OOP Encapsulation) refers to the bundling of data, along with the methods that operate on that data, into a single unit. Many programming languages use encapsulation frequently in the form of classes.

What is false constructor?

What is false about constructor? Explanation: The constructor cannot have a return type. It should create and return new objects. Hence it would give a compilation error.

What does abstraction mean Mcq?

Explanation: Abstraction is called stream to provide a level of complexity hiding, for how the files operations are actually done. Actual devices are called file because in one way or another, those can be considered as single entity and there is nothing hidden.

What is pop in programming?

POP Definition

Procedural Oriented Programming is one of the programming methods where the main focus is on functions or procedures required for computation, instead of data. The program is divided into functions, and the task is done sequentially.

What is object in C plus plus Mcq answer?

Object is datatype of a class. Object is an instance of a class.
