Technically it makes no difference. Since * and / have the same
precedence and are left-associative, a*b/c equals (a*b)/c. Furthermore
an integer division equals a floating point division which is followed
by a conversion to an int (at least if we limit ourselves to positive
numbers).
It may still be a good idea to make the expression clearer. But I
think
int empty_corner_value = (EMPTY_CORNER_VALUE * board_size) / 19;
would be a cleaner solution.
