Object-oriented programming is one technique of raising the level of abstraction by means of which the programmer communicates with the computer: from the level of flipping individual bits on and off, from the level of punching holes in paper cards, from the level of extraordinarily complex sequences of basic instruction codes, from the level of less complicated definitions of reusable templates for blocks of data and reusable blocks of code (structs and procedures), to the level of transcribing the concepts in the programmer's mind into code, so that what goes on inside the computer comes to resemble, for the programmer, what goes on outside the computer in the world of physical objects, intangible assets, and cause-and-effect.
