Lexical Analysis • A lexical analyzer collects input characters into groups (lexemes) and assigns an internal code (a token) to each group. • Lexemes are recognized by matching the input against patterns. • Tokens are usually coded as integer values, but for the sake of readability, they are often referenced through named constants.
