How to use Inheritance in cpp with example

 

 

 

Inheritance:

• In C++, inheritance is the mechanism by which one class can inherit the properties of another.
• When one class is inherited by another, the class that is inherited is called the base class. The inheriting class is called derived class.
• Base class is also known as parent class or old class. Derived class is also known as child class or new class.
• Remember constructor never inherits.
• Structure in C++ also supports inheritance.

Syntax for inheritance

class base-name

{
  …

};

class derived-name : visibility mode base-name

{
 …

};

• Syntax covers two classes, one is base class and other is derived class.
• During derived class definition, notice a colon (:) followed by visibility mode and then comes base class name. This addition to derived class definition tells the compiler about linking between two classes.
• Members of base class now also consider members of derived class.
• Membership category for the base class members in derived class are defined by visibility mode.
• Visibility modes are private, protected and public.
• In class, when no visibility mode is mentioned, it is private by default.
• In structure, when no visibility mode is mentioned, it is public by default.

Visibility Modes

• Whatever may the visibility mode, private members of base class never inherits.
• When visibility mode is private, all protected and public members of base class become private members of derived class.
• When visibility mode is protected, all protected and public members of base class become protected members of derived class.
• When visibility mode is public, all protected members of base class become protected members of derived class and all public members of base class become public members of derived class.
