Why does the [] operator in vector behave as it does?

[Ted Byers]

Hi All,

An option Eljay didn't mention, which I use almost all
the time (certainly every time I may have a large
number of objects of a given UDT, as I always manage
such collections with one of the STL containers), is
to store your objects on the heap and manage them
through smart pointers (I prefer those in boost - but
any that have the right semantics for STL containers
will do).  They are assignable, and will take care of
deleting your objects at the right time.

HTH
