COMP3190: Principle of Programming Languages

COMP3190: Principle of Programming Languages. Formal Language Syntax. Motivation. The problem of parsing structured text is very common Consider the structure of email addresses (using a grammar): <emailAddress> := <person> @ <host> <person> := <word> <host> := <word> | <word>.<host>

LESSON 10

LESSON 10. Overview of Previous Lesson(s). Over View. Symbol tables are data structures that are used by compilers to hold information about source-program constructs. Information is put into the symbol table when the declaration of an identifier is analyzed.

Example. Simplify a regular expression:

Distinct regular expressions may represent the same language: a + b and b + a represent the same language { a , b }. Two expressions R and S that represent the same language, L ( R ) = L ( S ), are considered equal . For example, a + a * = a *
