#

you have a do-while loop

#

and that one never ends

#

the break; only breaks out of the switch

#

so everything after the while(true); can never be reached

grizzled rampart
#

ohh okok wait

#

soo what do i have to do to fix this?

rocky gulch
#

your switch always does the "ended" thing, so you don't even really need the loop

#

but seems like that's a separate mistake

#

you can label the loop to break out of the right statement:

loop:
while (...) {
  switch (x) {
    case "a": break loop;
  }
}

#

i mean, you actually need the label first

#

the loop: is important

grizzled rampart
#

idk anymore😭

fiery parrot
#

you need to do it before the do{

grizzled rampart
#

so like this?

image.png
fiery parrot
#

yes

grizzled rampart
#

well i did that and it still said undefined label for loop

fiery parrot
#

Can you show your whole code again?

#

and please format it properly

#

your switch isn't in the do while

#

you just have a stray block outside the loop
