Trying to make a Hiragana guesser

Hi, for one of my classes I've been trying to make a hiragana guesser, but when I run it nothing shows on the command window. I'm new to matlab so maybe I just made a mistake, but as far as I check I see nothing wrong. Does it have something to do with the symbols? When I run it here the symbol does appear, but the input does not work.

a=("あ");
i=("い");
u=("う");
e=("え");
o=("お");
rand=randi(5);
    switch rand
        case 1
            disp(a)
            hg=input("Insert Kana \n");
            if hg==a
                fprintf("Correct")
            else
                fprintf("Incorrect")
            end
        case 2
            disp(i)
            hg=input("Insert Kana \n");
            if hg==i
                fprintf("Correct")
            else
                fprintf("Incorrect")
            end
        case 3
            disp(u)
            hg=input("Insert Kana \n");
            if hg==u
                fprintf("Correct")
            else
                fprintf("Incorrect")
            end
        case 4
            disp(e)
            hg=input("Insert Kana \n");
            if hg==e
                fprintf("Correct")
            else
                fprintf("Incorrect")
            end
        case 5
            disp(o)
            hg=input("Insert Kana \n");
            if hg==o
                fprintf("Correct")
            else
                fprintf("Incorrect")
            end
    end

う

Unable to run the 'fevalJSON' function because it calls the 'input' function, which is not supported for this product offering.

rand = 2

    switch string(rand)

い

hg = "い"

Correct

The input function cannot work in online editor, but certainly it does when its run in a PC installed with MATLAB

rand=randi(5)

rand = 2

switch string(rand)
    case '1'
        disp('something')
    case '2'
        disp('something')
end

something

[VBBV]

use a string expression in defining the swtich case statements

[VBBV]

Also, use strcmp when comparing the input strings with hiragana characters

Thank you it worked and now I can expand it to the rest of the hiragana alphabet.

Yes. It's shown in my comment to your question. If it worked for you please accept the answer. Thank you
