title: remove non alphabet characters from string c++
body: <p>I'm trying to remove all non alphabet characters from an inputed string in c++ and don't know how to.  I know it probably involves ascii numbers because that's what we're learning about.  I can't figure out how to remove them.  We only learned up to loops and haven't started arrays yet.  Not sure what to do.  </p>
  
  <p>If the string is <code>Hello 1234 World&amp;*</code><br>
  It would print <code>HelloWorld</code></p>
