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.

Why study compilers?

Why study compilers?. Ties lots of things you know together: Theory (finite automata, grammars) Data structures Modularization Utilization of software tools You might build a parser. The theory of computation/formal language still applies today.
