# A report on Formal language, Programming language and Computer science

In logic, mathematics, computer science, and linguistics, a formal language consists of words whose letters are taken from an alphabet and are well-formed according to a specific set of rules.

- Formal languageA 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 languageIn computer science, formal languages are used among others as the basis for defining the grammar of programming languages and formalized versions of subsets of natural languages in which the words of the language represent concepts that are associated with particular meanings or semantics.

- Formal languageProgramming language theory is a subfield of computer science that deals with the design, implementation, analysis, characterization, and classification of programming languages.

- Programming languageProgramming language theory is a branch of computer science that deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features.

- Computer scienceFormal methods are best described as the application of a fairly broad variety of theoretical computer science fundamentals, in particular logic calculi, formal languages, automata theory, and program semantics, but also type systems and algebraic data types to problems in software and hardware specification and verification.

## Logic

Study of correct reasoning or good arguments.

One prominent approach associates their difference with the study of arguments expressed in formal or informal languages.

Logic is studied in and applied to various fields, such as philosophy, mathematics, computer science, and linguistics.

Intuitionistic logic is of great interest to computer scientists, as it is a constructive logic and sees many applications, such as extracting verified programs from proofs and influencing the design of programming languages through the formulae-as-types correspondence.
