Pre-increment vs. post-increment.

The effect of this difference depends on the context,
and the nature of the object being incremented.

For a stand-alone operation, there is no difference with 
POD objects. That is, both

++x;
x++;

increment variable x by one.

Whatever is in the 3rd argument of a for() statement
gets executed/evaluated AFTER (at the end of) each 
iteration of the loop. Therefore, there is no difference
in the effect of ++r  vs. r++ in this case.
