I strongly favor the first syntax since it matches how I'd write it in
a for loop.
i.e. I'd replace [] with [i].
This is the best way to see array operations I've read up to now:
replace [] with [i], i being the current loop index. It's so simple to
explain.
If there was a sin variant that took array input, then I'd expect the
line to be:
x[] = sin(y)[]
which would translate to creating a temporary to hold sin(y) array.
Makes sense too.
this:
for(int i = 0; i < x.length; i++) {
x[i] = sin(y)[i];
}
makes sense?
Yes, if as stated by Jason there was a sin variant that took array input.
That said, I'd expect the compiler to call sin(y) only once, so it'd be
more like that:
auto sinY = sin(y);
for(int i = 0; i < x.length; i++) {
x[i] = sinY[i];
}
