Consider the following grammar:
$$\eqalign{ & S \to FR \cr & R \to *S\,|\,\varepsilon \cr & F \to id \cr} $$In the predictive parser table, M, of the grammar the entries $$M\left[ {S,id} \right]$$ and $$M\left[ {R,\$ } \right]$$ respectively.
Consider the grammar
$$S \to \left( S \right)\,|\,a$$Let the number of states in SLR(1), LR(1) and LALR(1) parsers for the grammar be n1, n2 and n3 respectively.
The following relationship holds goodConsider the grammar
$$E \to E + n\,|\,E \times n\,|\,n$$For a sentence n + n × n, the handles in the right-sentential form of the reduction are
Consider the following expression grammar. The semantic rules for expression calculation are stated next to each grammar production.
$$\eqalign{ & E \to number\,\,\,\,\,E.val = number.val \cr & \,\,\,\,\,\,\,\,\,\,\,|E\,\,' + '\,\,E\,\,\,\,\,\,{E^{\left( 1 \right)}}.val = {E^{\left( 2 \right)}}.val + {E^{\left( 3 \right)}}.val \cr & \,\,\,\,\,\,\,\,\,\,\,|\,E\,\,' \times '\,\,E\,\,\,\,\,\,\,{E^{\left( 1 \right)}}.val = {E^{\left( 2 \right)}}.val \times {E^{\left( 3 \right)}}.val \cr} $$The above grammar and the semantic rules are fed to a yacc tool (which is an LALR (1) parser generator) for parsing and evaluating arithmetic expressions. Which one of the following is true about the action of yacc for the given grammar?
