Case label for switch statement

---

  statement  := case  constant-expression  :  statement  

The case keyword labels a statement in a switch statement. A single statement can have multiple labels. You cannot use case outside of a switch statement.

Note that case labels have no effect on the order in which substatements are executed within a switch statement. Use the break statement to exit from a switch statement.

Example

 switch(c) {  case  '+':   z = add(x, y);   break;  case  '-':   z = subtract(x, y);   break; }
