-# Статично и динамично свързване. Виртуални функции. Полиморфизъм. Абстрактни класове.

-#### Статично и динамично свързване. Виртуални функции.

-Пример за **статично** свързване:

-```c++

-#include <iostream>

-using namespace std;

-

-struct A

-{ 

-    void f() const 

-    {

-	std::cout << "A::f()" << std::endl;

-    }	

-};

-

-struct B : public A

-{

-    void f() const 

-    {

-	std::cout << "B::f()" << std::endl;

-    }	

-};

-

-int main()

-{

-	B* bPtr = new B();

-

-	A* aPtr = bPtr;

-	

-	bPtr->f(); // B::f()

-	aPtr->f(); // A::f()

-}

- ```

-

- - **Статично** свързване - изборът на функцията, която трябва да се изпълни става **по време на компилация**.

- - **Динамично** свързване – изборът на функцията, която трябва да се изпълни става **по време на изпълнение на програмата**.

-

-```c++

-#include <iostream>

-using namespace std;

-

-struct A

-{

-    virtual void f() const 

-    {

-	std::cout << "A::f()" << std::endl;

-    }	

-};

-

-struct B : public A

-{

-    void f() const 

-    {

-       std::cout << "B::f()" << std::endl;

-    }	

-};

-

-int main()

-{

-	А* ptrs[2];

-	ptrs[0] = new A();

-	ptrs[1] = new B();

-	

-	ptrs[0]->f(); // B::f()

-	ptrs[1]->f(); // B::f()

-}

- ```

-#### Полиморфизъм

-Едни и същи действия се реализират по различен начин в

-зависимост от обектите, върху които се прилагат.

-

- - Действията се наричат полиморфни.

- - Реализира се чрез виртуални функции.

- - Класовете, върху които ще се прилага, трябва да имат общ родител или прародител, т.е. да са наследници на един и същ клас.

- - В класа се дефинира виртуален метод, съответстващ на полиморфното действие.

- - Всеки клас предефинира или не виртуалния метод.

- -  Активирането става чрез указател към базов клас, на който може да се присвоят адресите на обекти на който и да е от базовите класове от йерархията

-

-**Важно!** При полиморфна йерархия ще изтриваме обектите чрез указатели от базовия клас. За да се извикват правилните деструкори задължително **деструкторът на базовият клас** трябва е деклариран като виртуален!

-```c++

-#include<iostream>

-

-struct Animal

-{

-	virtual void sayHello() const

-	{

-		std::cout << "Hello, I am a random animal" << std::endl;

-	}

-

-	virtual ~Animal(){} //!!!

-};

-struct Dog : public Animal

-{

-	void sayHello() const override

-	{

-		std::cout << "Hello, I am a dog!" << std::endl;

-	}

-};

-

-struct Cat : public Animal

-{

-	void sayHello() const override

-	{

-		std::cout << "Hello, I am a cat!" << std::endl;

-	}

-};

-

-struct Mouse : public Animal

-{

-};

-

-int main()

-{

-	Animal** animals = new Animal*[3];

-

-	animals[0] = new Dog();

-	animals[1] = new Cat();

-	animals[2] = new Mouse();

-

-

-	//from base-class pointer

-	animals[0]->sayHello(); // Hello, I am a dog!

-	animals[1]->sayHello(); // Hello, I am a cat!

-	animals[2]->sayHello(); // Hello, I am a random animal!

-

-	delete animals[0], animals[1], animals[2];

-	delete[] animals;

-}

-

- ```

- #### Абстрактен клас

- 

-

- - Чисто виртуална функция (**pure virtual function**) - вруална функция без тяло.

- - Клас е **абстрактен**, ако в него има поне една **чисто виртуална функция**.

-

-Тогава класът е предназначен единствено за наследяване и няма да може да създаваме обекти от него.

-Така във всеки наследник ще трябва да се разпише имплементация на функцията. Ако някой наследник няма собствена имплементация, то и той става абстрактен клас.

-

-```c++

-#include<iostream>

-

-struct Animal

-{

-	virtual void sayHello() const = 0;

-

-

-	virtual ~Animal(){} //!!!

-};

-struct Dog : public Animal

-{

-	void sayHello() const override

-	{

-		std::cout << "Hello, I am a dog!" << std::endl;

-	}

-};

-

-struct Cat : public Animal

-{

-	void sayHello() const override

-	{

-		std::cout << "Hello, I am a cat!" << std::endl;

-	}

-};

-

-struct Mouse : public Animal

-{

-	void sayHello() const override

-	{

-		std::cout << "Hello, I am a mouse!" << std::endl;

-	}

-};

-

-struct PrehistoricAnimal : public Animal

-{};

-

-int main()

-{

-	// Animal* pa1 = new Animal(); No! Animal is an abstract class!

-	// Animal* pa2 = new PrehistoricAnimal(); No! PrehistoricAnimal is also an abstract class!

-

-	Animal** animals = new Animal*[3];

-

-	animals[0] = new Dog();

-	animals[1] = new Cat();

-	animals[2] = new Mouse();

-

-

-	//from base-class pointer

-	animals[0]->sayHello(); // Hello, I am a dog!

-	animals[1]->sayHello(); // Hello, I am a cat!

-	animals[2]->sayHello(); // Hello, I am a random animal!

-

-	delete animals[0], animals[1], animals[2];

-	delete[] animals;

-}
