Are the C++ Standard Library functions and classes included in every C++ implementation?
<p>I was just curious because in my homework it says that the following statement is <em>false</em>:</p>

<blockquote>
  <p>The C++ Standard Library functions and classes are not included in every C++ implementation.</p>
</blockquote>

<p>I don't think that the Standard Library is included in every C++ implementation unless you add (<code>#include</code>) the appropriate headers, right? In that case, I think that the above statement is <em>true</em>, not <em>false</em>.</p>

<p>Is the statement <em>true</em> or <em>false</em>?</p>
