I am not entirely sure if our school compilers are updated for C++11 so I will have to log onto our CSE Machines to check that out.  I will look into everything to see what I should do.  
 
I also probably should make sure I'm allowed to use any of those from the standard library.  Professor has been somewhat picky on us using the standard library in some places.

You don't have to use the standard library for it. Even if you don't have move-semantics (one move cost for moving the last element over the deleted element) you could still do a simple copy (just making it one copy cost).

<array element at elementToDelete> = <array element at lastElement>

That's alot faster than...
for every element above elementToDelete
: <previous element> = <current element>

But, as mentioned, doesn't preserve the relative order of the elements - which may have been part of the class assignment's requirements.
