EBNF
EBNF stands for Extended Backus-Naur Form. It is a meta-language used to describe the syntax of programming languages, data formats, and communication protocols. EBNF is an extension of the Backus-Naur Form (BNF) and provides additional syntax to describe complex grammars. EBNF uses a set of symbols to represent the elements of a grammar, such as terminals, non-terminals, and meta-symbols. Terminals are the basic building blocks of a language, such as keywords, operators, and punctuation marks. Non-terminals are symbols that represent a group of terminals or other non-terminals. Meta-symbols are used to define the structure of the grammar, such as repetition, optional elements, and grouping. EBNF is widely used in the development of programming languages, compilers, and parsers.
