Switch Statement

[Drew Lane]

Is it possible to have a switch statement in which the cases define a range?

switch(available){

case < 100:
// do this
break;

case >=100:
// do this
break;

}

Thanks!

No. Best you could do is this:

switch(test) {
 case 0:
 case 1:
 case 2:
    ...
 case 100:
    // do something
    break;
 case 101:
    // do something else 
    break;
 
}

Not very good. Better use an if statement.

Paul is correct.
No is the answer.

The switch statement came from C.

There is was used as an optimization. There are certain kinds of comparisons that the compiler can optimize. Exact comparisons of simple values. They are much easier to identify and optimize when they are using a different syntax.

The optimization could not take place if it was a range, so there was no reason to add that.

My personal opinion is that you should almost always use if rather than switch.

Not you can't do this.
the case of switch can't have condition for test.
