What is Inheritance in OOP(Object Oriented Programming) ?

• Inheritance is the process by which one object can acquire the properties of another object.

• In reality as Children get properties from Parents. Similarly in OOP(Object Oriented Programming) using inheritance a Child class can extends the data and member from its parent class.

• There are various types of inheritance, based on paradigm and specific language.

1. Single inheritance : Where subclasses inherit the features of one super class. A class acquires the properties of another class.  
   
2. Multiple inheritance: Where one class can have more than one super class and inherit features from all parent classes. 
   
3. Multilevel inheritance : Where a subclass is inherited from another subclass. Hierarchical inheritance: Where one class serves as a superclass (base class) for more than one sub class. 
   
4. Hybrid inheritance: a mix of two or more of the above types of inheritance.
