Hi there, I am creating an algorithm to sort screw sizes. I need the user to input the screw size and whether or not to continue (until there are no more screws to sort). I cannot get the while loop to work correctly. I would like to ask the user "Continue? y/n: " and if the user types y, then the loop would continue, and if n, then the loop would stop and display my output. My problem is that I need to ask for the screw size and whether or not to continue every time the loop executes, so it would have to be in the while loop somehow, but that doesn't make sense because I need to initialize the while loop beforehand. Any help would be appreciated!
Thanks,

while true
ask for input
if the input was not 'y'
break
end
ask for a screw size
do whatever
end

x = []; % This will store screw Sizes
while true
loop = input('Continue? (1/0) : '); % 1 to continue 0 to break loop
if loop == 1
screwSize = input('Enter screw size : ');
x = [x screwSize];
else
break
end
end
sort(x)
