Correct.  A language-level array is not an STL container.

There IS a shared_ptr-like template called shared_array that calls "delete
[]" instead of "delete".  Had to look that one up.  It doesn't get used
much.  std::vector is a superior choice (in every situation I can think of).

An STL container of shared_ptr's is just fine.  Just don't create a circular
reference.

Subject: [Boost-Users] shared_ptr capabilities

http://www.boost.org/libs/smart_ptr/shared_ptr.htm states that:
 "Normally, a shared_ptr cannot correctly hold a pointer to a dynamically
allocated array. See shared_array for that usage."

What I hope to use shared_ptr for, is to store pointers to a class in a
vector, and that class will also have a vector that stores pointers via
shared_ptr.

example:

class Foo {
    int a;
}

class one {
    int var1;
    int var2;
    std::vector<Foo>         foo_vector;
}

class two {
    std::vector<one>         one_vector;
}

I don't believe the above statement will affect me, but I just want to be
sure
