int main()

    int n, k;
    int i = 10;
    int j = 0;
    int numray[11];
    
    numray[0] = 0;
    
    printf("ENTER A NUMBER...\n");
    scanf("%d", &n);
    printf("ENTER THE KTH DIGIT FROM THE RIGHT...\n");
    scanf("%d", &k);
    while (n / i != 0)
    {
        n %= i;
        i *= 10;
        j += 1;
        numray[j] = n;
        
        if (j == k)
        {
            printf("Your kth integer is %d \n", numray[j]);
        }
    }
    
}```

The above code does not display a number for any k which is not 1  /:

When your question is answered use !solved to mark the question as resolved.

perhaps you shouldnt multiply i by 10 in the loop

knotty delta
#

in theory, you should do
n last_dig

829 -> 9
82 -> 2
8 -> 8
done

#

you are doing:
n last_dig

829 -> 9
9 -> done

#

perhaps think about how n is modified to go from 829 to 82

Have you tried stepping through your code line by line in a debugger?

If you don't know how to use a debugger or don't have one set up, we highly recommend taking the time to do so.
Debuggers are immensely helpful tools for figuring out where problems emerge in code and especially when you're first learning it can help you build intuition and understanding for reasoning through code.

Resources:

#

debuggers are cool things to help see what really is happenning, step by step

#

you can even use paper and pencil, that's a totally acceptable debugger team for a problem like this

#

like making a table of variables, how they change each step
