Euclid’s theorem There are infinitely many prime numbers. The Pythagorean theorem If a, b, and c are sides of a right-angled triangle, and c is the side opposite the right angle, then a2 + b2 = c2. The remainder theorem If a polynomial p(x) is divided by (x – r) , the remainder is p(r) The factor theorem A polynomial p(x) has a factor (x ...
Structured text, abbreviated as ST or STX, is one of the five languages supported by the IEC 61131-3 standard, designed for programmable logic controllers (PLCs). [1] [2] It is a high level language that is block structured and syntactically resembles Pascal, on which it is based. [3] All of the languages share IEC61131 Common Elements.
ISPF. In computing, Interactive System Productivity Facility ( ISPF) [1] is a software product for many historic IBM mainframe operating systems and currently the z/OS and z/VM operating systems that run on IBM mainframes. It includes a screen editor, the user interface of which was emulated by some microcomputer editors sold commercially ...
Literate Programming by Donald Knuth is the seminal book on literate programming.. Literate programming is a programming paradigm introduced in 1984 by Donald Knuth in which a computer program is given as an explanation of how it works in a natural language, such as English, interspersed (embedded) with snippets of macros and traditional source code, from which compilable source code can be ...
Jan 2, 2019 · The landmark book in the technique was "Structured Programming" (Academic Press 1972), which contained three sections: "Notes on Structured Programming" by Edsger W. Dijkstra, "Notes on Data Structuring" by C.A.R. Hoare, and "Hierarchical Program Structures" by Ole-Johan Dahl and C.A.R Hoare. The last section introduced Simula and its object ...
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ). In OOP, computer programs are designed by making ...
