Final Words : References or Pointers

[eye51]

Hi,

There are already many threads of this on this forum. But again asking related question, so please excuse me !!!

I have gone through lot of material on the internet regarding using References and Pointers. But still could not finally come to any significant conclusion. Hence, please experts guide me.

If I want to pass a big vector class (non-const) to a function/constructor. What should I adopt, References or Pointers?

Efficiency
Speed-up
Memory copy (stack stuff)

Which is the best way for writing efficient code?

Suggestions will be welcome.
Thanks.

There's no difference in performance.
Use pointers if the parameter is optional (i.e. it can be 0), references otherwise.
