Which Of The Following Advantage We Lose By Using Multiple Inheritance?

What is the biggest reason for the use of polymorphism?

What is the biggest reason for the use of polymorphism.

Explanation: Polymorphism allows for the implementation of elegant software.

Which among the following can show polymorphism?

Which among the following can show polymorphism? Explanation: Only insertion operator can be overloaded among all the given options. And the polymorphism can be illustrated here only if any of these is applicable of being overloaded. Overloading is type of polymorphism.

What are the disadvantages of multiple inheritance?

The disadvantage of multiple inheritance is that it can lead to a lot of confusion(ambiguity) when two base classes implement a method with the same name.

What is a base class?

A base class is also called parent class or superclass. Derived Class: A class that is created from an existing class. The derived class inherits all members and member functions of a base class. The derived class can have more functionality with respect to the Base class and can easily access the Base class.

What is single inheritance in C++?

Single Inheritance: In single inheritance, a class is allowed to inherit from only one class. … Multiple Inheritance: Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. i.e one sub class is inherited from more than one base classes.

What is inheritance with an 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.

Why do we need multiple inheritance?

Most people use multiple-inheritance in the context of applying multiple interfaces to a class. This is the approach Java and C#, among others, enforce. C++ allows you to apply multiple base classes fairly freely, in an is-a relationship between types. So, you can treat a derived object like any of its base classes.

Which of the following best describes multiple inheritance?

Which among the following best describes multiple inheritance? Explanation: If a class inherits more than one class, it is known as multiple inheritance. This should not be referred with only two or three classes being inherited.

Why do we use inheritance?

One of the most important concepts in object-oriented programming is that of inheritance. Inheritance allows us to define a class in terms of another class, which makes it easier to create and maintain an application. This also provides an opportunity to reuse the code functionality and fast implementation time.

Which among the following is called first automatically whenever an object is created?

Constructors1. Which among the following is called first, automatically, whenever an object is created? Explanation: Constructors are the member functions which are called automatically whenever an object is created.

What is meant by multiple inheritance?

Multiple inheritance is a feature of some object-oriented computer programming languages in which an object or class can inherit characteristics and features from more than one parent object or parent class.

Which of the following shows multiple inheritance in C++?

Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B’s constructor is called before A’s constructor.

What is multiple inheritance explain with example?

Multiple inheritance occurs when a class inherits from more than one base class. So the class can inherit features from multiple base classes using multiple inheritance. This is an important feature of object oriented programming languages such as C++. A diagram that demonstrates multiple inheritance is given below −

What is single and multiple inheritance?

Single inheritance is one in which the derived class inherits the single base class. Whereas multiple inheritance is one in which the derived class acquires two or more base classes.

Why multiple inheritance is not allowed?

Java supports multiple inheritance through interfaces only. A class can implement any number of interfaces but can extend only one class. Multiple inheritance is not supported because it leads to deadly diamond problem.

What is meant by polymorphism?

Polymorphism means “many forms”, and it occurs when we have many classes that are related to each other by inheritance. Like we specified in the previous chapter; Inheritance lets us inherit attributes and methods from another class. Polymorphism uses those methods to perform different tasks.

Which of the following shows multiple inheritances?

Which of the following shows multiple inheritances? Explanation: In multiple inheritance, a single class is inherited from two classes.

What are the things inherited from the base class?

In most class-based object-oriented languages, an object created through inheritance, a “child object”, acquires all the properties and behaviors of the “parent object” , with the exception of: constructors, destructor, overloaded operators and friend functions of the base class.
