Give an example to explain Data Abstraction.

What is meant by Data Hiding? 

Give two differences between Data Hiding and Encapsulation.

'Encapsulation reduces the complexity and makes the system easier'. Explain this statement with a real world example.

Give two differences between Procedure Oriented languages and Object Oriented languages.
