        This rule is deprecated, and will eventually be removed.

        Why is this an issue?

        Empty case clauses that fall through to the default are useless. Whether or not such a case is present, the default clause will be invoked. Such cases simply clutter the code, and should be removed.

        Noncompliant code example

        switch(ch)
        {
          case 'a' :
            handleA();
            break;
          case 'b' :
            handleB();
            break;
          case 'c' :  // Noncompliant
          default:
            handleTheRest();
            break;
        }
        

        Compliant solution

        switch(ch)
        {
          case 'a' :
            handleA();
            break;
          case 'b' :
            handleB();
            break;
          default:
            handleTheRest();
            break;
        }
