Regular Expressions | Dr.V.Savitha | SNSInstitutions

This video dives into the concept of Regular Expressions as a core component of lexical analysis in Compiler Design. It explains how regular expressions are used to define token patterns for identifiers, literals, operators, and reserved words. You'll see how they are converted into Finite Automata (NFA/DFA) for implementation in lexical analyzers like Lex. The video also covers the connection between regular expressions and regular languages in the Chomsky hierarchy. With examples and automata illustrations, this video is ideal for students preparing for GATE, technical interviews, or anyone wanting a deeper understanding of compiler theory.
