Consider the translation scheme shown below

$$\eqalign{ & S \to TR \cr & R \to + T\left\{ {pr{\mathop{\rm int}} (' + ');} \right\}\,R\,|\,\varepsilon \cr & T \to num\,\left\{ {pr{\mathop{\rm int}} (num.val);} \right\} \cr} $$

Here num is a token that represents an integer and num.val represents the corresponding integer value. For an input string '9 + 5 + 2', this translation scheme will print

Consider the grammar shown below.

$$\eqalign{ & S \to CC \cr & C \to cC\,|\,d \cr} $$

This grammar is

A shift reduce parser carries out the actions specified within braces immediately after reducing with the corresponding rule of grammar.

$$\eqalign{ & S \to xxW\,\left\{ {pr{\mathop{\rm int}} \,'1'} \right\} \cr & S \to y\,\left\{ {pr{\mathop{\rm int}} \,'2'} \right\} \cr & W \to Sz\,\left\{ {pr{\mathop{\rm int}} \,'3'} \right\} \cr} $$
