递归下降解析算法（Recursive Descent Parsing）是一种自上而下的解析技术，广泛应用于编译器和解释器的设计中，用于分析编程语言或任何形式语言的语法结构。它根据给定的文法规则（通常采用巴科斯范式，即BNF形式）来解析输入串，通过一系列的函数调用模拟文法规则的递归定义，从而识别出输入中的语法结构。一、基本原理 递...

To learn how recursive descent parsers work, it is helpful to implement a very simple grammar, so for pedagogical purposes, I’ve defined a grammar for simple arithmetic expressions. The parser will construct a syntax tree from expressions that we can then examine as necessary. Just for fun, ...
What is Recursive Descent Parser - Recursive Descent Parser uses the technique of Top-Down Parsing without backtracking. It can be defined as a Parser that uses the various recursive procedure to process the input string with no backtracking. It can be s

If you want an interpreter, a recursive descent parser will at the same time evaluate the expression, so there is no need to hold it in memory. If you want a compiler, then a constant expression like the example can and should be optimised, but most expressions will operate on variables,...
