Yes, even without the parenthesis a compiler is required to get an answer
appropriate for doing the division first. However there is considerable
confusion about this. In my printing of C++PL 3rd, BS writes that the
parenthesis are required if you want to be sure of the result of a*b/c. IMO
any mistake that BS makes is likely to be repeated by compiler
implementations.
(C++PL third, First printing, page 123, last paragraph of section 6.2.2
Evaluation Order).
