Chapter 2: Creative Development

Computing Innovations

  • Computing has spurred creativity in medicine, engineering, communications, and the arts.

  • Quantitative data is used by health insurance companies to choose providers.

  • Heart monitor watches take blood pressure continuously.

  • Microprocessor-controlled artificial legs and blind reading apps improve quality of life.

  • Computing innovations can help artists mix media.

  • Simulations can predict real-world outcomes based on changing variables.

Hardware Vs. Software

  • Hardware is the physical components of a computing device, while software is the instructions in a programming language to the computing device.

  • A computing innovation can have hardware components.

  • However, the computing innovation is about the software, not the hardware.

Collaboration

  • Collaboration helps people learn from each other.

  • Collaboration that includes diverse perspectives helps to avoid bias in the development of computing innovations.

  • Effective collaboration can help one gain insight and knowledge by applying multiple perspectives, experiences, and skill sets.

  • Collaboration with others can make the programmer more self-aware.

  • Collaboration facilitates the solving of computational problems by applying multiple perspectives and skill sets.

  • Collaboration combines different individuals’ resources, talents, and experiences.

How Programs Function

  • A program is a collection of program statements that performs a specific task when run by a computer.

  • A program is often referred to as software.

  • A code segment refers to a collection of program statements that are part of a program.

Example of a program

Program Input

  • Program input is data sent to a computer for processing by a program.

  • Input can come in a variety of forms, such as tactile, audio, visual, or text.

  • For example, a cell phone can convert voice (audio) to text to send a message.

Development Process

Program Documentation

  • Program documentation is a written description of the function of a code segment, event, procedure, or program and how it was developed.

  • Program documentation helps in developing and maintaining correct programs when working individually or in collaborative programming environments.

  • Programmers should document a program throughout its development.

  • Documentation helps the programmer remember what he or she was thinking or the collaborative partners were thinking at the time they were programming.

Program Errors

  • Logic error—This is a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.

  • Syntax error—This is a mistake in the program where the rules of the programming language are not followed.

  • Runtime error—This is a mistake in the program that occurs during the execution of a program.

    • Programming languages define their own runtime errors.
