|---|---|---|---|---|---|
| structured programming | Guidelines for an organized, logical approach to programming that focuses on high-level thinking. Rather than simply writing code line by line, the programmer thinks in terms of structured groups of instructions.
🗑
|
||||
| routine | A section of a program that accomplishes a specific part of the programming task.
🗑
|
||||
| modular code | Code that is written using modules, which are self-contained sections of a program’s overall source code that can be reused in other areas of the program or in other programs.
🗑
|
||||
| modularity | A measurement of how well the source code is divided into individual modules.
🗑
|
||||
| object-oriented programming (OOP) | An extension of the modularity concept that goes further by defining each module—called an object—with definite rules for interfacing and a protected set of variables. OOP forces exacting rules on programmers.
🗑
|
||||
| object | A module. See also modular code.
🗑
|
||||
| rapid application development (RAD) | A set of programming methods designed to reduce labor costs by employing early prototyping rather than extensive written descriptions in the design phase and by using high-level languages with good user interface design capabilities.
🗑
|
||||
| Agile software development | A software development philosophy that radically redefines the accepted methods of software development by focusing on the values published in the Agile Manifesto.
🗑
|
||||
| bug | A computer error.
🗑
|
||||
| debugger | A software tool that helps programmers find errors quickly.
🗑
|
||||
| documentation | Written documents that explain how a program works.
🗑
|
||||
| flowchart | A diagram that provides a visual picture of an algorithm. A programmer can draw a flowchart showing the logic of a program with symbols that represent operations.
🗑
|
||||
| computer-aided software engineering (CASE) tools | Suites of powerful applications that are specifically designed to help teams of software developers with project management, programming, and user testing.
🗑
|
||||
| comment | An informational message inserted into the program source code, normally used to explain source code to programmers who may later examine and modify the code.
🗑
|
||||
| hacking code | Writing code without carefully planning and structuring the program so that many errors occur because the programmer was sloppy during the programming process.
🗑
|
||||
| logic error | An error that occurs when a program’s syntax is correct but the program instructs the computer to perform an action incorrectly.
🗑
|
||||
| run-time error | An error that appears when an application is running.
🗑
|
||||
| crash bug | A bug that causes a program to stop running, or crash.
🗑
|
||||
| infinite loop | A programming mistake that causes a program to perform the same set of instructions over and over again, without any way of stopping.
🗑
|
||||
| style error | A programming mistake that makes the program slower to execute or bulkier than it would otherwise be.
🗑
|
||||
| dead code | Code that is marked as a comment so that the compiler ignores it.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
