Programming paradigms and languages

Programming language features exist to provide building blocks to be combined to express programming ideals. Ideally, a programming language should:

The programming style of a programming language to provide these building blocks may be categorized into programming paradigms. For example, different paradigms may differentiate:

Each of these programming styles has contributed to the synthesis of different programming languages.

A programming language is a set of keywords, symbols, identifiers, and rules by which programmers can communicate instructions to the computer. They follow a set of rules called a syntax.

Programming languages get their basis from formal languages. The purpose of defining a solution in terms of its formal language is to generate an algorithm to solve the underlining problem. An algorithm is a sequence of simple instructions that solve a problem.
