<h3>no_conststringconv</h3>
<p>  Disables the deprecated implicit const string literal conversion (ISO C++, &sect;4.2).  </p>
<h5>Syntax</h5>
  <p class="code">#pragma no_conststringconv on | off | reset
  </p>
  <h5>Targets</h5>
  All platforms.<br />
  <h5>Remarks</h5>
  <p>When enabled, the compiler generates an error when it encounters an implicit const string conversion. See example in Listing 10.27.</p>
  <div class="listing">
      <h4>Listing 10.27 Example of const string conversion</h4>
      <p>#pragma no_conststringconv on<br />
      char *cp = &quot;Hello World&quot;; // generates error: illegal<br />
      // implicit conversion from <br />
    // &rsquo;const char[12]&rsquo; to &rsquo;char *&rsquo;</p>
  </div>
  <p>This pragma does not correspond to any panel setting. To check this setting, use <span class="code">__option (no_conststringconv)</span><span class="code"></span>, described in <a href="../symbols/sym_settings.htm">Checking Settings</a>. The default setting is off.</p>
