Part 2 Lexical analysis

Regular expressions are equivalent to finite automata deterministic. (DFA) or non-deterministic (NFA). Finite automata are easily turned into computer programs.

Lexical Analysis

Regular Expressions and Definitions specify sets of strings over an input alphabet. They can hence be used to specify the set of lexemes associated with a token
