Is it possible to add a static variable to a C++ struct?
<p>I am getting the following error when trying to add a static variable to my struct:</p>

<blockquote>
  <p>Undefined Symbole s2::aa in module
  file_name.cpp</p>
</blockquote>

<p><code>s2</code> is the name of the structure and <code>aa</code> is the static variable.
The compiler I am using is Turbo C++ 3.0.</p>

<p>How do I fix this error?</p>
