Multiple labels are permitted in a switch-section. The example. switch (i) { case 0: CaseZero (); break; case 1: CaseOne (); break; case 2: default: CaseTwo (); break; } I believe in this particular case, the GOTO can be used, and it's actually the only way to fallthrough.

For something this simple an if/else structure could be clearer and simpler, depending on the compiler your case statement may be translated into a series of branching comparison statements anyways.
