Types of Inheritance

1. Single Inheritance
2. Multiple  Inheritance
3. Multilevel Inheritance
4. Hierarchical  Inheritance
5. Hybrid Inheritance

1.Single Inheritance:

• Here only one base class and one derived class is allowed.
• In the figure A is base class and B is derived class.

2.Multiple Inheritance:

• Here class A and class B are base class and class C is derived class.
• Class C have properties of class A and class B.

3.Multilevel Inheritance:

• Here class E is Base class.
•  Class A is intermediate class and  Class B is derived class.

4.Hierarchical Inheritance:

• Here Class a is base class.
• Class B, Class C and Class D are derived classes.

5.Hybrid Inheritance:

• Combination of any two types of above inheritance is called Hybrid Inheritance
