Sure, and it happens a lot:
switch(justification) {
case kLeft:
case kCenter:
case kRight:
DoRegularReflow();
break;
case kFullJustifyNormal:
case kFullJustifyEvenLastLine:
DoJustifiedReflow();
break;
}
If I ever have a case that has code AND falls through, I make sure I mark it as
such in lieu of a break:
case 0:
Something();
break;
case 1:
printf("Hey, it's doing that thing you wanted to know about.\n");
// Fall through!
case 2: {
NSString* s = [self getString];
Blah(s);
break;
}
