[gameprogrammer] Iterator question/organize a vector

Hi guys,
I'm just double checking on how to use iterators in my game. I have a list
of words, and the potential to re-arrange their order. Is this the correct
manner in which to do so with iterators:
a vector called "word", with iterator #1 (iter1) and iterator #2 (iter2).
iter2 is always the next vector element after iter1. (iter2 = iter1++)
in the event that I need to switch the two words, does this c++ code work?
word.insert(iter1,*iter2);
word.erase(iter2);
will this give me the expected result? or will I erase what's pointed to by
iter1, since I just added something in front of it, essentially putting it
in the place where iter2 has been pointing?
Thanks for the help!
-Dave
