Behavior of printf

[sewilli]

Wanting to make sure the following leads to defined behavior (i.e. C standard). . .

double x1, x2, n;
x1 = . . .
x2 = . . .

printf("%f %f %f %f", modf(x1, &n), n, modf(x2, &n), n);

Are the arguments always evaluated left to right so that printf would report the intended value of n in each case?

Thanks.

I don't have the Standard right here (it's at home)

But function arguments are not evaluated in a defined order. And I don't see any reasons why it should be different with variadic functions.

So my conclusion: sorry, it doesn't lead to defined behavior (it's implementation defined)

Thanks for the reply. It's good to know even if it's not the answer I'd hoped for.
