title: Conditions that won't accept letters from the alphabet
body: <blockquote>
  <p>How do make a condition in c++ that says you can't put letters from
  the alphabet? Well, I know how to do it manually but is there any way
  that you can't do it manually? I tried using the java code method but
  it didn't work(well it won't work really because it's from java not
  CPP)</p>

  <pre><code>if(choice == 'A-Za-z')
  {
  cout&lt;&lt;&quot;No alphabet please&quot;&lt;&lt;endl;
  }
  </code></pre>
