Translational Backus–Naur form
Translational Backus-Naur Form (TBNF) is a way to describe a programming language in a structured and organized manner. Imagine if you had to write a recipe for a cake but instead of using normal English words, you had to use a special kind of language that only people who know how to bake understand. TBNF is like that special kind of language for describing programming languages.
TBNF helps people to understand how to write code for a specific programming language. It describes the different parts of the language using what's called syntax rules. These rules are like instructions that tell you how to put words and symbols together in a way that makes sense to the computer.
To use TBNF, we start by breaking down the programming language into its individual parts, like words and punctuation. Then we define each part using TBNF rules. For example, in many programming languages, a statement starts with a keyword like "if" or "while". We would define the "if" keyword using a TBNF rule like this:
if_statement ::= "if" expression "then" statement
This rule tells us that an "if" statement must start with the keyword "if", followed by an expression (which is a fancy word for something like a math equation), and then the keyword "then". After that, there is a statement (which is another piece of code).
Using TBNF lets us create a clear and consistent description of a programming language's syntax, so that everyone who writes code in that language can follow the same rules. It's like a special language that helps programmers communicate with the computer.
