We'll explore the vital function of a lexical analyzer, sometimes referred to as a lexer or scanner, in the compilation process in this video. Comprehending the first stage of compilation requires an understanding of how lexical analyzers translate source code into meaningful tokens. This tutorial teaches about tokenization, regular expressions, and lexical error handling. It explains how a lexical analyzer breaks source code into tokens, which are the smallest units of meaning in a programming language. It also explains how these patterns guide the lexical analyzer in recognizing and extracting tokens.
