Code examples

The following code example fails the check and will give a warning:

int example(int x) {
  switch(x){
    default:
      return 2;
      break;
  }
}

The following code example passes the check and will not give a warning about this issue:

int example(int x) {
  switch(x){
    case 3:
      return 0;
      break;
    case 5:
      return 1;
      break;
    default:
      return 2;
      break;
  }
}
