No

The only things that case be used inside a switch statement are constants or enums.
Anything else will give you a 


constant expression required


error. That is something like this is not valid


switch(i)
{
  case 1: // Something; 
          break;
  case j: // Something;
          break;
}



So is this. You cannot switch() on strings


switch(i)
{
  case "string1" : // Something; 
                   break;
  case "string2" : // Something;
                   break;
}




This is valid, however


switch(i)
{
  case 1:     // Something; 
              break;
  case 1*2+4: // Something;
              break;
}


This is also valid, where t is an enum


switch(i)
{
  case 1: // Something; 
          break;
  case t: // Something;
          break;
}


Also note that the default case does not require a break; if and only if its at the
end of the switch() statement. Otherwise, even the default case requires a break;
