You can, you just need to put them, and the code that uses them inside curly braces, thus:
C++
switch (number)
{
case 1:
    {
        int i; // local to only this case statement
    }
}

Variables not inside such a block are considered to have the scope of the entire switch block. But if they are declared in a single case statement there is a possibility that they would not get initialised safely. To make a variable available to multiple case statements it must be declared before the switch.
