No.

"Evaluation Order

Unless otherwise specified, the implementation is free to evaluate the 
components of an expression in any order. It is an error to depend on 
order of evaluation when it is not specified. For example, the following 
are illegal:

i = ++i;
c = a + (a = b);
func(++i, ++i);

If the compiler can determine that the result of an expression is 
illegally dependent on the order of evaluation, it can issue an error 
(but is not required to). The ability to detect these kinds of errors is 
a quality of implementation issue."
