Thanks!
I will take care of the indentation and fix the comment.
> I think the indentation warnings should catch that?
I get this:
void f()
{
}
} // <- error: expected identifier or '(' before '}' token
I ran with -Wall -Wextra -pedantic and did not see a indentation
warning. Am I missing some indentation warning? The error message I
get is a little misplaced. I think it's fine to warn about that } but
it could also say in the error message that the problem is probably
the previous }
> Should this say something like "expected ) or , or ;"?
No none of those suggestions will solve the error.
Look at this code:
int x = 3) + 0;
Writing a ) or , or ; will not fix the syntax error. You have to
remove the ) or add a ( somewhere.
