2. Context-free grammar - Wikipedia

   en.wikipedia.org/wiki/Context-free_grammar

   In formal language theory, a context-free grammar (CFG) is a formal grammar whose production rules can be applied to a nonterminal symbol regardless of its context. In particular, in a context-free grammar, each production rule is of the form. with a single nonterminal symbol, and a string of terminals and/or nonterminals ( can be empty).

3. Compiler - Wikipedia

   en.wikipedia.org/wiki/Compiler

   Program execution. In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming ...

4. Terminal and nonterminal symbols - Wikipedia

   en.wikipedia.org/wiki/Terminal_and_nonterminal...

   In formal languages, terminal and nonterminal symbols are the lexical elements used in specifying the production rules constituting a formal grammar. Terminal symbols are the elementary symbols of the language defined as part of a formal grammar. Nonterminal symbols (or syntactic variables) are replaced by groups of terminal symbols according ...

   Backus–Naur form. In computer science, Backus–Naur form (/ ˌbækəs ˈnaʊər /) (BNF or Backus normal form) is a notation used to describe the syntax of programming languages or other formal languages. It was developed by John Backus and Peter Naur. BNF can be described as a metasyntax notation for context-free grammars.

9. "Hello, World!" program - Wikipedia

   en.wikipedia.org/wiki/"Hello,_World!"_program

   A "Hello, World!" program is generally a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!" while ignoring any user input. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
