Using the syntax of c, write a recursive descent subprogram that corresponds to the following ebnf production (taken from the specification of java): → [ final ] { , } ; {, }, [, and ] are metasymbols. assume that the token codes for final, the comma, and the semicolon are final_code, comma_code, and semicolon_code, respectively. also assume that recursive-descent subprograms named type and variable_declarator already exist.
