Abstraction literally means hiding. Now in OOP the
intention is to hide the complexity. For this reason
generally the data in classes is protected. THis data is
accessible to the functions(some times called behaviour).
OK! now for a user creating an application, it is easier to
use functions using the objects of class rather than
manipulating the data itself. This is how abstraction
works. Abstraction is a conceptual theory or a way of doing
things, not a must.
