Quick Pseudocode Question (1 Viewer)

'Sup guys
firstly, the name is innovative and funny, lol 'Bored of Studies'

Anyways,
in pseudocode, there is multiway selection. (more than 2 options). Is it necessary to have a CASE ELSE statement?

examples

is this correct?

SELECT CASE choose ice cream topping
Case CHOC: select chocolate flavoured topping
Case STRAW: select strawberry flavoured topping
CASE ELSE: select no topping/do nothing
END CASE

or

SELECT CASE choose ice cream topping
Case CHOC: select chocolate flavoured topping
Case STRAW: select strawberry flavoured topping
Case NONE: select no topping for icecream.
END CASE

so it necessary for a 'CASE ELSE' statement?

Thanks verymuch.

SELECT CASE choc topping
CASE CHOC: choose choc
CASE STRAW: choose straw

DEFAULT : choose none

that is how most programing is done using a DEFAULT, but for psuedocode, i was told it is not a language so u are able to make up most stuff as long as it makes sense so yes u could use CASE NONE or ELSE most teachers would understand but the best would be DEFAULT as it used in real programming and it makes sense as well

Ty buddy.

CASEWARE select
Choc : choc topping
Straw : straw topping
OTHERWISE : no topping
ENDCASE

OTHERWISE is what my class has been using. It's best to do that, it just fits better than CASE NOTHING. My teacher is very pedantic with things like that. I think CASE ELSE/OTHERWISE is necessary as you're restricting the user if you're forcing them to pick a few options. Better to be safe than sorry.
