What is the difference between parsers?

Can you explain the difference between a parser and a lexer?

Sure! A lexer breaks down the input text into tokens, while a parser takes those tokens and builds a structure, like a syntax tree.

What types of parsers are there?

There are several types of parsers, including top-down parsers, bottom-up parsers, and recursive descent parsers.

When would I use a specific type of parser?

You might choose a top-down parser for simpler grammars and a bottom-up parser for more complex ones, depending on your needs.

Can you give an example of a parser in programming?

Certainly! In programming languages, parsers like ANTLR or yacc are commonly used to interpret code and generate syntax trees.
