Inheritance
Ø Single level inheritance :
Ø Multi-level inheritance :
Example of multiple
inheritance:
Inheritance is the process of forming a new class
from an existing class or base class.
The base class is also known as parent class or
super class, the new class that is formed is called derived class.
Derived class is also known as a child class or
sub class. Inheritance helps in reducing the overall code size of the program,
which is an important concept in object-oriented programming.
It is classifieds into different types, they are
Ø Single level inheritance :
Example
of single level inheritance:
class Base
{
};
class Derv: public Base
{
{
};
class Derv: public Base
{
};
Ø Multi-level inheritance :
Example
of multi level inheritance:
class A
{
};
class B: public A
{
{
};
class B: public A
{
};
class C: public B
{
{
};
Ø Multiple
inheritance : One class being derived from multiple parent classes.
Example of multiple
inheritance:
class
A
{
};
class B
{
{
};
class B
{
};
class C: public B, public A
{
{
};
Ø Hybrid
inheritance :
Example of hybrid inheritance:
Example of hybrid inheritance:
class
A
{
};
class B
{
{
};
class B
{
};
class C: public A, public B
{
{
};
class D: public A
{
{
};
class X: public D, public C
{
{
};
Ø Hierarchial
inheritance :
Example of hierarchical inheritance:
Example of hierarchical inheritance:
class
A
{
};
class B: public A
{
{
};
class B: public A
{
};
class C: public A
{
{
};
