Question

For switch statements, is it possible to change the value of the switch inside the switch statement so that it can jump around to different cases?
Ex:

int w = 0;
switch(w)
{
   case 1:
     doSomething();
     w = 3;
   case 2:
     doSomething();
     break;
   case 3:
     doSomething();
     break;
}

Basically what I’m asking is, if I do not place a break statement for a case and I change the value of the switch in the same case, will the code execute both cases?

Answer 1

Yes you can change the value inside switch but it will not execute case for new value until you break in the case where you changed the value.

In your case it will not go in any case as there is no case for 0. But if you change to w = 1 then it will go for case 1 and then for case 2 as you do not have break; but it will not go for case 3.
