What means operator "slash" for C++ string? : <p>In a C++ code I found a line</p>

<p><code>std::string   fruit = "" / "apple";</code></p>

<p>When stepping with Visual Studio 12 over this line, the <code>fruit</code> variable ends up containing <em>apple</em>.
But <strong>what means this operator "/"</strong> for <code>std::string</code> ?</p>
