In computing, source code, or simply code or source, is text (usually plain text) that conforms to a human-readable programming language and specifies the behavior of a computer. A programmer writes code to produce a program that runs on a computer.
Polyspace is a static code analysis tool for large-scale analysis by abstract interpretation to detect, or prove the absence of, certain run-time errors in source code for the C, C++, and Ada programming languages. The tool also checks source code for adherence to appropriate code standards.
macOS. The Finder is the default file manager and graphical user interface shell used on all Macintosh operating systems. Described in its "About" window as "The Macintosh Desktop Experience", it is responsible for the launching of other applications, and for the overall user management of files, disks, and network volumes.
In computer programming and software design, code refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality .
Codebase. In software development, a codebase (or code base) is a collection of source code used to build a particular software system, application, or software component. Typically, a codebase includes only human-written source code system files; thus, a codebase usually does not include source code files generated by tools (generated files ...
Software design pattern. In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it.
The function \verb+isValidDate+ test if date is valid \begin{code} isValidDate :: Date -> Bool isValidDate date = hh>=0 && mm>=0 && ss>=0 && hh<24 && mm<60 && ss<60 where (hh,mm,ss) = fromDate date \end{code} observe that in this case the overloaded function is \verb+fromDate :: Date -> (Int,Int,Int)+.
In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software,: 7 following the reusability principles.
Most software projects speed up their development by reusing or incorporating existing software, either in the form of commercial off-the-shelf (COTS) or open-source software. [35] [36] Software quality assurance is typically a combination of manual code review by other engineers [37] and automated software testing .
Program comprehension. Program comprehension (also program understanding or [source] code comprehension) is a domain of computer science concerned with the ways software engineers maintain existing source code. The cognitive and other processes involved are identified and studied. [1]
