Code refactoringIn computer programming and software design, code refactoring is the process of restructuring existing source code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, or implementation of the software (its non-functional attributes), while preserving its functionality.
Comment (computer programming)In computer programming, a comment is text embedded in source code that a translator (compiler or interpreter) ignores. Generally, a comment is an annotation intended to make the code easier for a programmer to understand – often explaining an aspect that is not readily apparent in the program (non-comment) code. For this article, comment refers to the same concept in a programming language, markup language, configuration file and any similar context.
Cyclomatic complexityCyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program's source code. It was developed by in 1976. Cyclomatic complexity is computed using the control-flow graph of the program.
Code smellIn computer programming, a code smell is any characteristic of source code that hints at a deeper problem. Determining what a code smell is and is not is subjective, and varies by language, developer, and development methodology. The term was popularized by Kent Beck on WardsWiki in the late 1990s. Usage of the term increased after it was featured in the 1999 book Refactoring: Improving the Design of Existing Code by Martin Fowler. It is also a term used by agile programmers.
Coupling (computer programming)In software engineering, coupling is the degree of interdependence between software modules, a measure of how closely connected two routines or modules are, and the strength of the relationships between modules. Coupling is not binary but multi-dimensional. Coupling is usually contrasted with cohesion. Low coupling often correlates with high cohesion, and vice versa.
Computer programmingComputer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit.
Source codeIn computing, source code, or simply code or source, is human readableplain text that can eventually result in controlling the behavior of a computer. In order to control a computer, it must be processed by a computer program – either executed directly via an interpreter or translated into a more computer-consumable form such as via a compiler.
CodebaseA codebase (or code base) is a collection of source code that is maintained as a unit. Typically, it is used to build one or more software components including applications and libraries. A codebase is often stored in a source control repository of a version control system. A repository can contain build-generated files (which are therefore not source code), but typically such files are excluded from a repository, and therefore the codebase.Software maintenanceSoftware maintenance is the modification of software after delivery. Software maintenance is often considered lower skilled and less rewarding than new development. As such, it is a common target for outsourcing or offshoring. Usually, the team developing the software is different from those who will be maintaining it. The developers lack an incentive to write the code to be easily maintained.
Statement (computer science)In computer programming, a statement is a syntactic unit of an imperative programming language that expresses some action to be carried out. A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components (e.g. expressions). Many programming languages (e.g. Ada, Algol 60, C, Java, Pascal) make a distinction between statements and definitions/declarations.
Whitespace characterA whitespace character is a characterdata element that represents white space when text is rendered for display by a computer. For example, a space character (U+0020SPACE, ASCII 32) represents blank space such as a word divider in a Western script. A printable character results in output when rendered, but a whitespace character does not.Source lines of codeSource lines of code (SLOC), also known as lines of code (LOC), is a software metric used to measure the size of a computer program by counting the number of lines in the text of the program's source code. SLOC is typically used to predict the amount of effort that will be required to develop a program, as well as to estimate programming productivity or maintainability once the software is produced.Variable (high-level programming language)In some high-level programming languages, a variable is an abstract storage or indirection location paired with an associated symbolic name, which contains some known or unknown quantity of data or object referred to as a value; or in simpler terms, a variable is a named container for a particular set of bits or type of data (like integer, float, string, etc...) or undefined.
