Polymorphism allows an entity (for example, variable, function or object) to take a variety of representations.

The classic example, Dogs and cats are animals, animals have the method makeNoise. I can iterate through an array of animals calling makeNoise on them and expect that they would do there respective implementation.

Here is the example explained:

class Animal

{

abstract string MakeNoise ();

}

class Cat : Animal {

string MakeNoise () {

return "Meow";

}

}

class Dog : Animal {

string MakeNoise () {

return "Bark";

}

}

Main () {

Animal animal = Zoo.GetAnimal (); //eg Dog so the line beneath would Bark

Console.WriteLine (animal.MakeNoise ());

}

Different OO languages use different methods to implement polymorphism such as:

Fuction overloading, Function overriding, operator overloading.

Polymorphism basically means one name many from or "one interface multiple methods"

this helps reduce complexity by allowing the same interface to be used to specify a general class of action

example-

Class A

{ void f1(int a)

{ ------

-----

}

void f1(int a,int b)

{ ------

-----

}

}

here function f1() is overloaded with one argument and two arguments... means "one name many forms" name of f1 function is same but it contains many forms like arguments...

Polymorphism is a feature of OOP, Polymorphism can be implemented using function overloading,operator over loading in C++, all the above examples are perfect. However in java operator over loading is not possible because all the operators are overloaded.

As rightly said polymorphism provides the same interface for different methods polymorphism is one of the most important feature provided by the object oriented programming function overloading constructor overloading operator overloading are some of the very interesting feature provided by polymorphism and there is two type of polymorphism runtime and compile time and also check out some already overloaded examples like printf scanf also

Polymorphism means that some code or operations or objects behave differently in different contexts. Functions overloading is also example of polymorphism, or some operators in C++ have polymorph feature, as example "+":

2+3 addition of integer numbers

"Hello"+"world" - string concatenation

Typically, when the term polymorphism is used with C++, however, it refers to using virtual methods:

Example of virtual method:

class Base

{public:

virtual void do_something()=0;

//do_something is undefined virtual method, we will define this method in child class

}

class child1:public Base

{public:

void do_something()

{cout

Polymorphism allows to derived classes replace the code of methods or properties of their ancestors.

Dear Imran

A mutation is defined as any change in a DNA sequence away from normal. This implies there is a normal allele that is prevalent in the population and that the mutation changes this to a rare and abnormal variant.

In contrast, a polymorphism is a DNA sequence variation that is common in the population. In this case no single allele is regarded as the standard sequence. Instead there are two or more equally acceptable alternatives.
