The DRY principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system". The principle has been formulated by Andy Hunt and Dave Thomas in their book The Pragmatic Programmer. [1] They apply it quite broadly to include database schemas, test plans, the build system, even ...
Here's an example of a transaction code written in ABAP, which is a programming language used in SAP systems: ``àbap DATA: lv_sender_account TYPE string, lv_recipient_account TYPE string, lv_amount TYPE p DECIMALS 2. lv_sender_account = '123456'. lv_recipient_account = '789012'. lv_amount = 100.00. START-OF-SELECTION.
Computer programming in the punched card era. Student programmers at the Technische Hochschule in Aachen, West Germany in 1970 using IBM 026 keypunches. Punched card from a Fortran program. From the invention of computer programming languages up to the mid-1970s, most computer programmers created, edited and stored their programs line by line ...
Keystroke programming describes a specific way of programming by which each keystroke on a device or application is recorded in some way and then played back so that the recorded key-presses can be repeated multiple times.
Computer 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.
A programmer, computer programmer or coder is an author of computer source code – someone with skill in computer programming. The professional titles software developer and software engineer are used for jobs that require a programmer.
Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality. A module interface expresses the elements that are provided and required by the module.
In computer programming, a magic number is any of the following: A unique value with unexplained meaning or multiple occurrences which could (preferably) be replaced with a named constant A constant numerical or text value used to identify a file format or protocol; for files, see List of file signatures
Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language commands for handling decisions. Specifically, conditionals perform different computations or actions depending on whether a programmer-defined Boolean condition evaluates to true or false. In terms of ...
