Redefine the grammar in a way that numbers are defined by regular expressions. That is, remove two grammar rules for number and digit nonterminals, and replace them with a single regular expres- sions for numbers. 2. Modify the grammar to define assignment statements with a syntax similar to C/C+, where ex- pressions are assigned to identifiers. Here are the steps: (a) Add identifier token ID to the CFG. You may define it with regular expressions (since identi- fiers are tokens). We have already seen how to define identifiers with regular expressions, in previous sessions. (b) Consider a nonterminal for assignment. Let's call this nonterminal assignment. You need to define a CFG rule that defines assignment. An assignment in C/C+ grammatically consists of an identifier (defined in previous step), folowed by equality symbol (a…arrow_forward1.
