title: HTTP Post Response parsing in C++
body: <p>I am writing puzzle bot, http server which upon hitting , renders a default page with text area to write code similar to <a href="http://codepad.org/" rel="nofollow">http://codepad.org/</a>. When I type in following program.</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  int main( int argc, char **argv) {
      return 0;
  }
  </code></pre>
  
  <p>I get following response from HTTP POST.</p>
  
  <pre><code>code : %23include+%3Cstdio.h%3E%0D%0Aint+main%28+int+argc%2C+char+**argv%29+%7B%0D%0A++++return+0%3B%0D%0A%7D
  lang : C
  </code></pre>
  
  <p>How Do I parse the information from the key <code>code</code>. I need to write this program in a temporary file and then compile/run.</p>
