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;
}
