Consider the following grammer for variable declarations:

  • <vardeel> $\rightarrow$ <vardeel><idlist> : <type>;
  • <vardeel> $\rightarrow \in$
  • <idlist> $\rightarrow$ <idlist>, id
  • <idlist> $\rightarrow$ id
  • <type> $\rightarrow$ integer
  • <type> $\rightarrow$ real


Write a syntax - directed translation scheme to install the identifiers into the symbol table. You must also issue appropriate error messages whereever necessary. Make suitable assumptions regarding procedures operating on the symbol table; you need not elaborate upon these procedures.
