Functions of Lexical Analyzer | Lexeme, Token & Pattern Explained | Compiler Design Tutorial

In this tutorial, we dive deep into the functions of a lexical analyzer and its crucial role in the compiler design process. Learn how the lexical analyzer works to convert source code into a stream of tokens, remove whitespace and comments, and recognize keywords, identifiers, and constants. We also discuss the important concepts of lexeme, token, and pattern and how they relate to each other. By the end of this video, you will have a solid understanding of how lexical analysis fits into the broader context of compilers and programming languages.
