Nested calling vs. Calling step by step [on hold]

Vote count:

Is it better, from complexity eye of view, to call a function and return its value to another function

a = foo();
bar (a);

Or to make a nested call?

bar(foo());

Indeed, I am making this millions of times.

If it depends on something else, please mention it.

You should go for clarity - the compiler should optimize the temporary away. But if it's critical, benchmark and look at the assembly code.
