Features of Object Oriented Programming

Encapsulation is a mechanism by which you restrict the access to some of the object’s components, as well as binding the data and methods operating on the data. Encapsulation is a way to obtain ‘information hiding’.

Abstraction is the process of moving from a specific idea to a more general one. For example take your mouse. “Silver Logitech MX518” is a concrete, specific item, and “mouse” is an abstraction of that.


Displaying multiple behavior. Achieved via virtual functions, operator overloading, function overloading, etc

Virtual Constructor:
