This example highlights one danger of abstraction in unusual situations, the simplified model may provide incorrect predictions. Note that this mental model is not really correct – pressing the gas provides torque to the wheels, which may or may not accelerate the car. As long as there is a mental model that the gas pedal makes the car go faster, the brake slows the car, and the steering wheel makes the car turn, a driver can be reasonably effective. For example, the driver of a car is not required to understand the mechanics of a car engine in order to drive. Abstraction Abstraction is the pruning away of complexity resulting in a simplified mental model of a process. Instead, computer programming relies upon the principal of abstraction to allow us to specify what actions a computer should perform. Direct control of such complexity is beyond our abilities. interpreted languages ✓ A simple C++ program ✓ Specifying variables ✓ Assignment and mathematical operations Programming Languages Computers are among the most complex artifacts made by humans and are comprised of billions of distinct elements. Some specific elements covered are: ✓ High-level computer languages ✓ Compiled vs. This chapter will look at a simple computer program. Computer programs are the means for specifying what actions a computer performs. Computers are tools for manipulating and analyzing information.
