who can tell me is it all right?

[Laurent R]

Hi,
  I reviewed some codes from one project. I think it is not proper, but I 
don't know the reason. Who can help me to explain it?
  I don't think it is proper that 'break' exists in the bracket. It seems 
not good that it remains in the local variable domain.
  Do you think it is all right?

EXAMPLE:
  switch (var)
{
case 1:
     {
         unsigned char ucTemp;
         ....(some operation)....
         break;
     }
case 2:
     {
         unsigned char ucTemp;
         ....(some operation)....
         break;
     }
default:
    break;
}
