Programming Language and its Applications

A programming language is a formal language which comprises a set of instructions used to produce various kinds of output. Programming languages are used to create programs that implement specific algorithms.

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 use other forms of program specification such as the declarative form (i.e. the desired result is specified, not how to achieve it).

Programmers use programming languages to communicate with computers. Many different languages exist, and each one has its own unique features, though they all share some similarities. Because each language is different, each may be best suited for a certain purpose or purposes within certain industries. Some programming languages are used to create programs to solve problems or interpret data. Other programming languages are more suitable for making create software or apps that entertain. With a strong need for unique and diverse programming languages, it is virtually impossible to create a single universal programming language that meets all needs. Programming languages are often revised and even combined with other languages over time, evolving to meet our changing technological needs.
