Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
ESC/P2 is a more recent variant of ESC/P by Epson. ESC/P2 is backward compatible with ESC/P, but adds commands for new printer features such as scalable fonts and enhanced graphics printing. ESC/P-R is a variant now used by Epson on many inkjet printers. [3] ESC/POS is a variant for controlling receipt printers as commonly used at the point of ...
A Nassi–Shneiderman diagram (NSD) in computer programming is a graphical design representation for structured programming. [1] This type of diagram was developed in 1972 by Isaac Nassi and Ben Shneiderman who were both graduate students at Stony Brook University. [2] These diagrams are also called structograms, [3] as they show a program's ...
In computer programming, a function (also procedure, method, subroutine, routine, or subprogram) is a callable unit [1] of software logic that has a well-defined interface and behavior and can be invoked multiple times. Callable units provide a powerful programming tool. [2]
Literate programming, as a form of imperative programming, structures programs as a human-centered web, as in a hypertext essay: documentation is integral to the program, and the program is structured following the logic of prose exposition, rather than compiler convenience.
This method of programming is easier than writing a complete function, as these skeleton functions do not have to include main functionalities and can instead be hardcoded to use during development. They usually involve syntactically correct code to introduce the method, as well as comments to indicate the operation of the program.
The structured program theorem, also called the Böhm–Jacopini theorem, [1] [2] is a result in programming language theory. It states that a class of control-flow graphs (historically called flowcharts in this context) can compute any computable function if it combines subprograms in only three specific ways ( control structures ).
Overlaying is a programming method that allows programs to be larger than the computer's main memory. [2] An embedded system would normally use overlays because of the limitation of physical memory , which is internal memory for a system-on-chip , and the lack of virtual memory facilities.
