State three differences between procedural and object-oriented programming.
Introduction to Object-Oriented Programming

Abstraction shows only the essential features of an object and hides the detail of how it works, so a user of a class needs to know only what its methods do. Encapsulation binds the data and the methods that act on it into one unit and restricts direct access to the data. Abstraction is about the design view; encapsulation is the mechanism that enforces it.
