What is Programming Language?
A programming language is any set of rules that converts strings, or
graphical program elements in the case of visual programming languages,
to various kinds of machine code output. Programming languages are one
kind of computer language, and are used in computer programming to
implement algorithms.
Most programming languages consist of instructions for computers. There
are programmable machines that use a set of specific instructions, rather
than general programming languages. Since the early 1800s, programs have
been used to direct the behavior of machines such as Jacquard looms, music
boxes and player pianos.
Thousands of different programming languages have been created, and more
are being created every year. Many programming languages are written in an
imperative form (i.e., as a sequence of operations to perform) while other
languages use 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 semantics (meaning), which are usually
defined by a formal language. Some languages are defined by a
specification document (for example, the
C programming language is
specified by an ISO Standard) while other languages (such as Perl) have a
dominant implementation that is treated as a reference. Some languages
have both, with the basic language defined by a standard and extensions
taken from the dominant implementation being common.
Programming language theory is a subfield of computer science that deals
with the design, implementation, analysis, characterization, and
classification of programming languages.
The history of programming languages actually dates back further than you
might think. Early computer codes date back to the early 1800s, and since
then, there are
9000
different programming languages.
