A derived class can inherit some or all of the features of the base class. A class can inherit features from more than one class and one or more than one level.
Based on these factors, the inheritance can be classified
into different types. They are
1. Single Inheritance
2. Multiple Inheritance
3. Multi Level Inheritance
4. Hierarchical Inheritance
5. Hybrid Inheritance
6. Multi-path inheritance
Single Inheritance:-
If a derived class is derived from only one base class, then
it is called “single inheritance‟.
Syntax:
class A
public:
…….
};
class B : public B
{
public:
…….
};
Multiple Inheritance:-
If a derived class is derived from more than one base class
is called “Multiple Inheritance‟.
Syntax:
class A
public:
---------
};
class B
{
public:
---------
};
class C : public A, public B
{
public:
---------
};
Multi Level Inheritance:-
If a derived class is derived from another derived class that
has been already derived from one base class, is called “Multi Level
Inheritance‟.
Syntax:
{
public:
---------
};
class B : public A
{
public:
---------
};
class C : public B
{
public:
---------
};
Hierarchical Inheritance:-
If number of derived classes are derived from a single base
class is called” Hierarchical Inheritance‟.
Syntax:
class A
{
---------
};
class B : public A
{
public:
---------
};
class C : public A
{
public:
---------
};
class D : public A
{
public:
---------
};
Hybrid Inheritance:-
Deriving a class that involves more than one form of
inheritance is called hybrid inheritance.
In the above example, it has both multi-level and
hierarchical inheritance. So, it shows hybrid inheritance.
Multi-path Inheritance:-
If a derived class is derived from other derived classes
which have been already derived from the same base class is called multi-path
inheritance. It forms grandparent, parent and child relationship.
