<p>Containers are collections of objects.</p>
<p>A container may hold any type which meets certain requirements, but the type of contained object is chosen at compile time, and all objects in a given container must be of the same type. (Polymorphism is possible by declaring a container of pointers to a base class and then populating it with pointers to instances of derived classes. Variant value types such as the <code>any</code> class from <a href="http://www.boost.org/">Boost</a> can also be used.</p>
<p>All contained types must be <code>Assignable</code> and <code>CopyConstructible</code>. Specific containers may place additional requirements on the types of their contained objects.</p>
<p>Containers manage memory allocation and deallocation themselves when storing your objects. The objects are destroyed when the container is itself destroyed. Note that if you are storing pointers in a container, <code>delete</code> is <em>not</em> automatically called on the pointers before destroying them.</p>
<p>All containers must meet certain requirements, summarized in <a href="tables.html">tables</a>.</p>
<p>The standard containers are further refined into <a class="el" href="a01683.html">Sequences</a> and <a class="el" href="a01684.html">Associative Containers</a>. <a class="el" href="a01685.html">Unordered Associative Containers</a>. </p>
