PROGRAMMING

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable computer programs. Programming involves activities such as analysis, developing understanding,  , verification of requirements of algorithms including their correctness and resources consumption, and implementation (commonly referred to as coding) of algorithms in a target .Source code is written in one or more programming languages (such as C, C++, C#, Java, phython, Ruby, smalltalk, java scriptetc.). The purpose of programming is to find a sequence of instructions that will automate performing a specific task or solving a given problem. The process of programming thus often requires expertise in many different subjects, including knowledge of the aplication domain, specialized algorithms and formal logic.

Related tasks include testing, debuggin, and maintaining the source code, implementation of the build system, and management of derived artifacts such as machine code of computer programs. These might be considered part of the programming process, but often the term "software development" is used for this larger process with the term "programming", "implementation", or "coding" reserved for the actual writing of source code. software engineering combines engineering techniques with software development practices.

A programming language is a formal constructed language designed to communicate instruction to a , particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.

The earliest programming languages preceded the invention of the digital computer and were used to direct the behavior of machines such as jacquads looms and player pianos Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. Many programming languages require computation to be specified in an imperative form (i.e., as a sequence of operations to perform), while other languages utilize other forms of program specification such as the declarative form (i.e. the desired result is specified, not how to achieve it).

The description of a programming language is usually split into the two components of syntax (form) and semantic (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages  have a dominant implementation that is treated as a referance
