Wait just kidding. I got it. It's because I have "else" on that line rather than "elseif". So then when would we ever use else? When we don't have any condition at all?
Why is this returning "logical 1"

This is my code:
userAge = input('How old are you?');
if userAge >0 && userAge <7
disp('Oh that''s so cute!')
elseif userAge >= 7 && userAge < 23
disp('What school do you go to?')
elseif userAge >= 23 && userAge < 65
disp('Do you work?')
elseif userAge >= 65 && userAge <=110
disp ('Are you retired yet?')
elseif userAge <0
disp ('That''s impossible.')
else userAge > 110
disp('That''s highly improbable.')
end
When I enter any number that is over 110 (like 112 or 956), Matlab returns this:
How old are you? 956
ans =
logical
1
That's highly improbable.
But with any other number, the "logical 1" does not come out. Is there something wrong with my code?
thank you!!

You might use ELSE as follows,
userAge = input('How old are you?');
if userAge >0 && userAge <7
disp('Oh that''s so cute!')
elseif userAge >= 7 && userAge < 23
disp('What school do you go to?')
elseif userAge >= 23 && userAge < 65
disp('Do you work?')
elseif userAge >= 65 && userAge <=110
disp ('Are you retired yet?')
elseif userAge <0
disp ('That''s impossible.')
else
disp('That''s highly improbable.')
end
