Outlines. v. t. e. Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
In computing, source code, or simply code or source, is text (usually plain text) that conforms to a human-readable programming language and specifies the behavior of a computer. A programmer writes code to produce a program that runs on a computer.
A computer program is a sequence or set [a] of instructions in a programming language for a computer to execute. It is one component of software, which also includes documentation and other intangible components. [1] A computer program in its human-readable form is called source code.
In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods).
The syntax of a language describes the form of a valid program, but does not provide any information about the meaning of the program or the results of executing that program. The meaning given to a combination of symbols is handled by semantics (either formal or hard-coded in a reference implementation ).
Program code is in blue. In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters.
Programming style, also known as coding style or code style, is a set of rules or guidelines that governs the layout of source code. Programming style may also refer an quality aspect of code that is interpreted subjectively. Some claim that following a particular programming style helps programmers read and understand code and to avoid ...
A program in machine code consists of a sequence of machine instructions (possibly interspersed with data)." [1] Each instruction causes the CPU to perform a very specific task, such as a load, a store, a jump, or an arithmetic logic unit (ALU) operation on one or more units of data in the CPU's registers or memory .
In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language).
A source-code editor is a text editor program designed specifically for editing source code of computer programs. It may be a standalone application or it may be built into an integrated development environment (IDE).
