The symbol table is one of the core data structures of a compiler. It is a repository of all the names declared in a program along with their types and other properties, and is organized into scopes. This chapter describes the structure and the operations of the symbol table. It also explains how to perform type checking using different forms of type compatibility. It finally shows how semantic information from the symbol table can be used to support parsing.
