An essential function of a compiler is to record the identifiers used in the source program and collect information about various attributes of each identifier, .These attributes may provide information about the storage allocated for an identifier, its type, its scope. A symbol table exists throughout the compilation and run-time.It is One of the most important data structures in every compiler is symbol table. Symbol table is a special data structure that holds all symbols, from identifiers to internally generated nodes.The data structure allows us to find the record for each identifier quickly and to store or retrieve data from that record quickly. When an identifier in the source program is detected by the lexical analyzer, the identifier is entered into the symbol table.
