If you want to maintain the pointer, I'd suggust you to store
pointers in vector. One problem for this technique is you'll
have to call operator delete explicitly when you remove elements
from vector. Using smart pointers (See Effective C++/More Effective C++
by Scott Meyers) solve the above problem.
Think of vector as a smart version of array that
can perform expand, insert, erase for you without having to write
everything yourself.
