I don't see what you're trying to achieve.

What you've shown is the equivalent of

if ( choice == '1' ) {
    do_selection();
    process_selected_item();
} else
if ( choice == '2' ) {
    process_selected_item();
} else {
}

With switch statements, you're limited to just omitting the break statement, to allow one case to 'fall through' into the next case. If the logic is more contrived than that, then you need to use if/else logic.

if you by 'nested case' means combining 2 cases in a switch statement by omitting the break between the 2, the answer is yes (At least I have done so a few times).

However I won't recommend it :

It's dangerous because you might overlook this later when/if adding more case statements.

Further you may spot the 'missing break' later and simply add the break - which will then cause the program to fail.

Hi,

Try this

case '1' :
case '2' :
do_selection();
process_selected_item();
break;
default:
break;
