5. (21 pts) Consider the following grammar for a declaration list: decl list decl ; decl-list | decl specifier type name-list specifier | static Etype double | int name list- name | name , name list name - id args args--( decl-list ) | const (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 D int f (double x); int f (double x, int y)
