title: C++ Multi-line comments using backslash
body: <p>Can // style comments be continued to the next line by using a back slash, like multi-line macros? E.g.</p>
  
  <pre><code>// here is a comment \
     and this is more comments \
  const char* x = "hello";  // this line of "code" is actually still a comment
  int x = 5; // and now an actual line of code
  </code></pre>
