Switch Statement

Syntax: switch ( Expression ) Statement

Semantics: The expression is computed and must of integer type (byte, int, or long) or of type char. If a matching case label is found within Statement, the execution jumps to that point. If not, the execution continues at the default label, if provided. Otherwise, Statement is skipped.

Syntax of case labels: case ConstantExpression :
default :

The labels come in front of a statement and multiple labels are permitted.

The break statement allows to leave a switch statement. Syntax: break ;

Layout according to our coding standard:
select ( Expression ) {
case Constant₁:
   StatementSequence_1a
   break;

case Constant₂:
case Constant₃:
   StatementSequence₂
   break;

default:
   StatementSequence₃
   break;
}

	Syntax: switch `(` Expression `)` Statement
	Semantics: The expression is computed and must of integer type (byte, int, or long) or of type char. If a matching case label is found within Statement, the execution jumps to that point. If not, the execution continues at the default label, if provided. Otherwise, Statement is skipped.
	Syntax of case labels: case ConstantExpression `:` default `:`
	The labels come in front of a statement and multiple labels are permitted.
	The break statement allows to leave a switch statement. Syntax: break `;`
