title: How do I increment letters in c++?
body: <p>I'm creating a Caesar Cipher in c++ and i can't figure out how to increment a letter.</p>
  
  <p>I need to increment the letter by 1 each time and return the next letter in the alphabet. Something like the following to add 1 to <code>'a'</code> and return <code>'b'</code>.</p>
  
  <pre><code>char letter[] = "a";
  cout &lt;&lt; letter[0] +1;
  </code></pre>
