In this video, we delve into the fascinating world of Lexical Analysis, an essential phase in the compilation process. Lexical analysis is the first step in the compilation process. It translates a sequence of characters from the source code into a sequence of tokens. This process is crucial for syntax analysis and ensuring the source code is free from basic syntax errors. We cover a variety of topics including an introduction to lexical analysis, the role of tokens, lexemes, and patterns, the function and significance of lexical analyzers (lexers), finite automata (both deterministic and non-deterministic), and the use of regular expressions in lexical analysis. Additionally, we explore the tokenization process and techniques for handling lexical errors.
