[cs13001] questions on unusual code

[Mikhail Nesterenko]

CSI students,

Here is something to think about for the next class. I encountered
this particular line in one of the project submissions:

     int *tmp = new int[size -= 1];

It does what it is untended to do. However, it is highly unusual. 
So, here are my questions:

    - what does the above line do?
    - why does it work?
    - how can it be simplified?

Thanks,
