title: Convert int to string/char C++/Arduino
body: <p>This has got to be the easiest thing to do in C++.</p>
  
  <p>..and I know it's been asked many many times before, however please keep in mind that this is part of an Arduino project and memory saving is a major issue as I've only got 32256 byte maximum to play with.</p>
  
  <p>I need to convert an integer to a string.</p>
  
  <pre><code>int GSM_BAUD_RATE;
  GSM_BAUD_RATE = 4800;
  
  Serial.println("GSM Shield running at " + GSM_BAUD_RATE + " baud rate.");
  </code></pre>
  
  <p>Obviously the last line is going to give me an error.</p>
  
  <p>Thanks in advance.</p>
