ANTLR C grammar, optional init_declarator_list?
- by eisbaw
Hello,
In the ANSI C grammar for ANTLR v3 ( http://antlr.org/grammar/1153358328744/C.g ), how can init_declarator_list be optional in rule declaration ?
Instead of:
| declaration_specifiers init_declarator_list? ';'
-I would say:
| declaration_specifiers init_declarator_list ';'
What part of the C standard allows statements like:
int;
EDIT:
I just tried, it is allowed! Okay then, why is it allowed?
