Syntax Notation is a system used to describe the structure of programming languages and formal languages. It provides a set of rules and symbols that define how statements and expressions can be formed. This notation helps programmers understand how to write code correctly and how different elements of a language interact with each other. Common forms of Syntax Notation include Backus-Naur Form (BNF) and Extended Backus-Naur Form (EBNF). These notations use specific symbols to represent grammar rules, making it easier to visualize the syntax of a language. By using Syntax Notation, developers can create parsers and compilers that interpret code accurately.
