switch statements evaluate an expression and then jump to the correct
case element. This can be done with multiple if-else statements but for many
branches a switch is generally easier to read. Formally,
switch ( expression ) {
case const-expr: statements;
case const-expr: statements;
default: statements;
}
Example:
switch ( var ) {
/*
* when var = 1 go here
*/
case ( 1 ):
printf ( "Got 1\n" );
break;
/*
* when var = 2 go here
*/
case ( 2 ):
printf ( "Got 2\n" );
break;
/*
* otherwise go here
*/
default:
printf ( "default clause\n" );
break;
}
