Defensive programming practices are often used where high availability, safety, or security is needed. Defensive programming is an approach to improve software and source code, in terms of: General quality – reducing the number of software bugs and problems.
An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
Although not meeting the definition of an infomercial per se, animated children's programming in the 1980s and early 1990s, which included half-hour animated series for franchises such as He-Man and the Masters of the Universe, My Little Pony, and Transformers, were often described as being marketing vehicles for related toy lines and tie-in ...
In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer.In contrast to low-level programming languages, it may use natural language elements, be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program ...
In computer programming, a sentinel value (also referred to as a flag value, trip value, rogue value, signal value, or dummy data) is a special value in the context of an algorithm which uses its presence as a condition of termination, typically in a loop or recursive algorithm.
Additionally, since a program spends most time executing a minority of its code, the reduced compilation time is significant. Finally, during the initial code interpretation, execution statistics can be collected before compilation, which helps to perform better optimization. [20] The correct tradeoff can vary due to circumstances.
Most programming languages include the concept of a subroutine or function, a mechanism that allows commonly used code to be encapsulated and re-used throughout a program.
In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. [1] [2] Heartbeat mechanism is one of the common techniques in mission critical systems for providing high availability and fault tolerance of network services by detecting the network or systems failures of nodes or daemons ...
