Efficiency is the same; the difference is when the "++" is evaluated, before or after other operations.
For example:
a = b++ // This will first copy b to a, then increment b.
a = ++b // This will first increment b, then copy it to a.
If you have the "++" operator by itself, it makes no different if you use prefix or postfix. a++ is the same as ++a.
