What is polymorphism in Object-oriented programming? Write down C# code example support the polymorphism
Polymorphism is the ability of any data to be
processed in more than one form. The word itself indicates the
meaning as poly
means
many and morphism
means types. Polymorphism is one of the most
important concept of object oriented programming language. 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.Polymorphism uses those methods to perform different tasks.
This allows us to perform a single action in different ways.
Polymorphism can be static or dynamic. In static polymorphism, the response to a function is determined at the compile time. In dynamic polymorphism, it is decided at run-time.
Static Polymorphism:-
The mechanism of linking a function with an object during compile time is called early binding. It is also called static binding. C# provides two techniques to implement static polymorphism. They are −
You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument list.
In the below code snippet print function The following example shows using function print() to print different data types −
Dynamic polymorphism:-
C# allows you to create abstract classes that are used to provide partial class implementation of an interface. Implementation is completed when a derived class inherits from it. Abstract classes contain abstract methods, which are implemented by the derived class. The derived classes have more specialized functionality.
//This code snippet is the example of static polymorphism in Which print function is defined in different forms to Print different data types. using System; namespace PolymorphismApplication { class Printdata { void print(int i) { Console.WriteLine("Printing int: {0}", i ); } void print(double f) { Console.WriteLine("Printing float: {0}" , f); } void print(string s) { Console.WriteLine("Printing string: {0}", s); } static void Main(string[] args) { Printdata p = new Printdata(); // Call print to print integer p.print(5); // Call print to print float p.print(500.263); // Call print to print string p.print("Hello C++"); Console.ReadKey(); } } } //Dynamic polymorphism example: using System; namespace PolymorphismApplication { class Shape { protected int width, height; public Shape( int a = 0, int b = 0) { width = a; height = b; } public virtual int area() { Console.WriteLine("Parent class area :"); return 0; } } class Rectangle: Shape { public Rectangle( int a = 0, int b = 0): base(a, b) { } public override int area () { Console.WriteLine("Rectangle class area :"); return (width * height); } } class Triangle: Shape { public Triangle(int a = 0, int b = 0): base(a, b) { } public override int area() { Console.WriteLine("Triangle class area :"); return (width * height / 2); } } class Caller { public void CallArea(Shape sh) { int a; a = sh.area(); Console.WriteLine("Area: {0}", a); } } class Tester { static void Main(string[] args) { Caller c = new Caller(); Rectangle r = new Rectangle(10, 7); Triangle t = new Triangle(10, 5); c.CallArea(r); c.CallArea(t); Console.ReadKey(); } } }

Questions are Object Oriented Programming with C++ related 1. Write a syntax to declare a static data member named count of a class named Base. 2. Can polymorphism be used with protected inheritance in C++? why or why not? 3. With a given code, how will you check whether the code applies polymorphism correctly?

Demonstrate through code and explanation each of the following object oriented concepts: Inheritance Encapsulation Polymorphism Discuss the advantages of applying object orienting coding principles.
The characteristic of object oriented programming that allows the method in subclass that overrides the same method in the superclass to be correctly called from an instance of that superclass is called A. abstractness B. polymorphism C. data binding D. inheritance
object oriented programming:Write a program that converts a number entered in decimal toRoman numerals. Your program should consist of a class, say, romanType. Anobject of type romanType should do the following:a. Store the number as a decimal.b. Convert and store the number into roman form.c. Print the number as a Roman numeral or decimal number as requestedby the user.The decimal values of the Roman numerals are:M 1000D 500C 100L 50X 10V 5I 1

QUESTION 36 Why do we want to use polymorphism when developing good Object Oriented solutions? One function call can have many different results, depending on the data type being sent in Prevents a developer from having to write many if statements to catch the different data types O Allows for cleaner and simpler code because we only use one function name with different signatures All of the above None of the above QUESTION 37 If my class PassTest implemented...
Some code in c ++ and its UML to apply inheritance and get and set methods, the code must be about computers, also applying object-oriented programming I need a code in C++ applying OOP with the topic of computers, then in the code must include the get method returns the variable value, and the set method sets the value.
Java is an object-oriented programming language that enables us to define classes and to instantiate them into objects. These objects then call each other’s methods to implement the behavior of the application. The Unified Modeling Language (UML) is an object-oriented visual notation to document the design of object-oriented classes. For this discussion, you will practice designing a Java class called Course, drawing a UML class diagram for the Course class, and then implementing the Course class in Java code. Review...
