Define Inhertance(BCA- 3rd sem)

Inharitance dafination

• Inheritance is an important feature of object oriented programming concept which describe different rule and regulation. A class can be define a return type value. It is a process in which one class acquire the property of another class with the help of object oriented concept. The old class in a program know as base class which transfer proper to new class know as derived class. The derived class inherit property of base class create a parent-child relationship.

Types of inheritance 

1). Single Inheritance

     

• A derived class with only one base class know as single inheritance with the help object oriented concept.

(2). Multiple inheritance 

• A derived class with many base class know as multiple inheritance 

3).Multi level inheritance

• The method of a derived class from another derived class is kown as multi level inheritance.

4). Hybrid inheritance 

• It support the concept of tree and multiple inheritance with the help of object oriented programming concept know as Hybrid inheritance. It means Hybrid inheritance combination of tree and multiple inheritance .

5). Tree inheritance

• The property of may be inherit by more than. One derived class know as tree inheritance.

6). Virtual base class inheritance 

• All three type of inheritance that is multilevel, multiple and tree in virtual base class inheritance. A class is made a virtual. Than C++ language take a necessary condition which check only one copy of the class is inherit.

Virtual base class inheritance example

Class A

{

   Member

   Function

} ;

  Class B1 : Virtual public A

{

     Member  function 

} ;

Class B 2 : Virtual public A

{

     Member function 

} ;

Class C : public B1 , public B2

{

      Member function 

} ;
