<h1> Boost </h1>

<p>

Boost is a large and diverse collection of open source libraries that extend the STL.

It is not part of the STL and is beyond the scope of this tutorial.

</p>

<h2> Boost Libraries </h2>

<p>

Here are listed a number of Boost libraries that may well have been included in C++ 11.

<ol><li>

The <b>array&lt;&gt;</b> class template is a fixed size array that meets most of

the requirements for a sequence container.

</li>

<li>

The <b>dynamic_bitset&lt;&gt;</b> class template is similar to the STL bitset&lt;&gt;

but its size can change at run-time.

</li>

<li>

The <b>binder</b> library generalises the STL bind1st&lt;&gt; and bind2nd&lt;&gt;

function templates and adds place-holders.

</li>

<li>

The <b>compose</b> library allows multiple functors to be combined into a single functor

for use with STL algorithms.

</li>

<li>

Boost generalises the STL <b>functor adaptors</b> &apos;mem_fun&apos; etc.

</li>

<li>

The <b>function</b> library provides a generic function wrapper library.

</li>

<li>

There is an alternative &lt;functional&gt; header file

that avoids the reference-to-a-reference issue.

</li>

<li>

There is a <b>lamba function</b> library that provides an alternative to the use of binders, composers and adaptors

and offers features of functional programming.

</li>

<li>

There are several <b>smart pointer</b> libraries that provide solutions to a number of problems with the STL auto_ptr&lt;&gt;.

</li></ol>
