When multiple cases require execution of identical code, then break statements may be omitted from all cases except the last one. Similarly, when processing for one case is a proper prefix of processing for one or more other cases, the break statement may be omitted from the prefix case. This should be clearly indicated with a comment. For example:
| Code Block | ||
|---|---|---|
| ||
int card = 11;
int value;
// Cases 11,12,13 fall through to the same case
switch (card) {
// MSC13-J:EX2: processing for this case requires a prefix
// of the actions for the following three
case 10:
do_something(card);
// intentional fall-through
// MSC13-J:EX2: these three cases are treated identically
case 11: // break not required
case 12: // break not required
case 13:
value = 10;
break; // break required
default:
// Handle Error Condition
}
