Guys as i beginner at coding, i need help with ending while loop when the user type 'q'. My codes are below.

I appreciate your help. Thanks!

clc

clear

syms q

syms a

while a ~= 'q'

a = input('Lutfen tam bolenlerini bulmak istediginiz sayiyi giriniz:')

disp('cikmak icin q tusuna basin.')

tam_bolenler = tambolenler (a)

end

function tambo = tambolenler (a)

if a > 0

y = 1;

tambo(1,y) = [0];

for i=1:a

if (mod(a,i)==0)

tambo(1,y) = i;

y = y+1;

end

elseif a < 0

y = 1;

tambo(1,y) = [0];

for i=-a:-1:a

if (mod(a,i)==0)

tambo(1,y) = i;

y = y+1;

end

else a==0

print("Bu program 0 degeri icin sonuc vermez...")

end

I'm going to ignore most of the tambolenler function, because I don't think it is needed to answer your question.

I think you have a few changes you need to make:

Remove the calls to syms q and syms a which are probably not doing what you think they are doing.
Initialize a as anything you want other than 'q'.
You need to tell the input command not to evaluate the user's input before returning the answer to you by adding the s flag, then separately use eval to evaluate the user input.
Switch from using ~= to ~isequal. The difference is that ~= is an element-by-element comparison while isqual compares the entire input variables.

a = '';
while ~isequal(a,'q')
    a = input('Lutfen tam bolenlerini bulmak istediginiz sayiyi giriniz:','s');
    disp('cikmak icin q tusuna basin.')
    if a ~= 'q'
        a = eval(a); % Convert from a character vector to a number.
        tam_bolenler = tambolenler(a);
    end
end

Happy to help. In the future, I suggest using the code formatting tools when posting your question. It makes the code much easier to read, and therefore you are much more likely to get a faster response.
