Question & Answer: Consider the following grammar for a declaration list:…..

Consider the following grammar for a declaration list:

decl_list → decl ; decl_list | ε

decl → specifier type name_list

specifier → const | static | ε

type → double | int

name_list → name | name , name_list

name → id args

args → ( decl_list ) | ε

(a) (4 pts) Indicate whether each of the following strings belongs to the language described by the grammar. int a (int b); int c (int d (int e;);); double f, g (static int h;); static int i; const double j;

(b) (7 pts) Show a leftmost derivation of the string static int f(); under this grammar.

(c) (10 pts) Rewrite the grammar so that arguments are separated by commas (similar to the function arguments in C). For instance, each of the following should be a valid string under the new grammar: int f (); int f (double x); int f (double x, int y);
