title: Why doesn't a simple "Hello World"-style program compile with Turbo C++?
body: <p>I have started learning C++ for my programming class. I have downloaded this "Hello World" program:</p>
  
  <pre><code>#include &lt;iostream&gt;
  using namespace std;
  
  int main() 
  {
      cout &lt;&lt; "Hello, World!";
      return 0;
  }
  </code></pre>
  
  <p>but Turbo C++ complains:</p>
  
  <pre><code>Error D:\HELLO.CPP 1: Unable to open include file 'IOSTREAM'
  Error D:\HELLO.CPP 2: Declaration syntax error
  Error D:\HELLO.CPP 6: Undefined symbol 'cout'
  </code></pre>
  
  <p>What's wrong with this very simple program? How can I correct these errors?</p>
