Defining Derived Classes, Protected, Private, Public Inheritance

Defining derived classes, Protected Inheritance, Private Inheritance, Public Inheritance Explain

Defining derived classes: -
 A class that uses inheritance to gain the behavior and data of another ('base') class is called derived class. A derived class is defined by specifying its relation ship with the base class in addition to its own details. The general form of defining a derived class is as follows.
    Class derived class_name : visibility-mode base-class-name
    {
    members of derived class;
    -----------
    };

1)    Public Inheritance :- 

Here the Child Class acquires the Protected and Public Members. And they Remain
       Protected and Public in the Child Class. Its done by using “public “ keyword during Child Class definition.
•    Each public member in the base class is public in the derived class.
•    Each  protected  member in the base class is protected in the derived class.
•    Each private member in the base class remains  private in the derived class.
 Class base-class name{                            };

 class  child-class-name : public  parent-class-name { definition of the child class};

2)    Private Inheritance :- 

Here the Child Class acquires the Protected and Public Members. And they  
             Become Private in the Child Class. Its done by using “private “ keyword during Child Class definition.
•    Each public member in the base class is private in the derived class.
•    Each  protected  member in the base class is private in the derived class.
•    Each private member in the base class remains private in the derived class and hence it is visible only in the base class.
  class base-class name{                            };

 class  child-class-name : private  parent-class-name { definition of the child class};

3)    Protected Inheritance :- 

Here the Child Class acquires the Protected and Public Members. And they Become Protected in the Child Class. Its done by using “protected “ keyword during Child Class definition.
•    Each public member in the base class is protected in the derived class.
•    Each  protected  member in the base class is protected  in the derived class.
             Each private member in the base class remains private in the derived class
  class base-class name{                            };

 class  child-class-name : protected  parent-class-name { definition of the child class};
