However, ordinary arrays don't + provide the interface of STL containers (although, they provide + the iterator interface of STL containers).</p> +<p>As replacement for ordinary arrays, the STL provides class + <code class="computeroutput">std::vector</code>. However, + <code class="computeroutput">std::vector<></code> provides + the semantics of dynamic arrays. Thus, it manages data to be able + to change the number of elements. This results in some overhead in + case only arrays with static size are needed.</p> +<p>In his book, <span class="emphasis"><em>Generic Programming and the + STL</em></span>, Matthew H. Austern introduces a useful wrapper + class for ordinary arrays with static size, called + <code class="computeroutput">block</code>. It is safer and has no worse performance than + ordinary arrays. In <span class="emphasis"><em>The C++ Programming + Language</em></span>, 3rd edition, Bjarne Stroustrup introduces a + similar class, called <code class="computeroutput">c_array</code>, which I (<a href="http://www.josuttis.com" target="_top">Nicolai Josuttis</a>) present + slightly modified in my book <span class="emphasis"><em>The C++ Standard Library - + A Tutorial and Reference</em></span>, called + <code class="computeroutput">carray</code>.
