# A report on Logic, Computer science and Formal language

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

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

- LogicComputer science research also often intersects other disciplines, such as cognitive science, linguistics, mathematics, physics, biology, Earth science, statistics, philosophy, and logic.

- 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.

## Programming language

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

Many important restrictions of this type, like checking that identifiers are used in the appropriate context (e.g. not adding an integer to a function name), or that subroutine calls have the appropriate number and type of arguments, can be enforced by defining them as rules in a logic called a type system.

## Mathematical logic

0 linksMathematical logic is the study of formal logic within mathematics.

These systems, though they differ in many details, share the common property of considering only expressions in a fixed formal language.

Computer scientists often focus on concrete programming languages and feasible computability, while researchers in mathematical logic often focus on computability as a theoretical concept and on noncomputability.
