help solving addition problem in C

[@$|-|. DUBEY]

i have a interger
val = 99999;
and i want to add the content of val i.e., 9+9+9+9+9 = 45;

how to do that....
need urgent help

take a temporary variable to store sum and initialize it to zero,
Now by recursively taking modulus and dividing the number you can each
digit separated and you can go on adding the digit..,

Hint:

val % 10 is the rightmost digit of val.
val / 10 shifts all digits to the right.

not only do you want help with your homework but you want the code as
well!
Another approach would be to use sprintf()

Thats good Always try to solve on your own or by following an
algorithm never expect a valid code.., It will help you a lot,

It's difficult to imagine how adding the digits of the decimal
representation of an integer could be "urgent". Unless, of course,
you're asking us to do your homework for you.

perhaps he's a number theorist or something. Tho' a 5
digit number seems kind of small. Ah! perhaps "interger"
isn't meant to be "integer" but indicates some other
mathematical object with more complex properties
(tho' Plain Old Integers a pretty complicated).
We need more info about these inergers of which you
speak.

Unless, of course,
you're asking us to do your homework for you.

good grief!

Hope it doesn't invoke any UB :)

/* given eg 54321, return 1 + 2 + 3 + 4 + 5. */
int my_sum(int n)
{
int sum = 0;

for (; n; n /= 10)
sum += n % 10;
return sum;
}

<entire Star Trek episode snipped before posting, with extreme prejudice>

The above seemed like a good idea at the time, but didn't turn out all that
well (I haven't had much practice writing ST scripts!), and I consigned it
to the bit bucket for the benefit of humanity. Suffice to say that they're
hiding in a ventilation shaft in an extremely expensive set^W^W alien city
on an SG-4 planet[1] and, for excellent reasons which never become readily
apparent, if they don't find the digital root of this astoundingly
enormous number *really* quickly, the Klingons will get the victory, the
universe, and the girl. The hero of the hour is a young programmer
named... well, that would be giving too much away, but anyway, although he
doesn't know how to calculate digital roots (this knowledge having long
since been lost to the human race), he *does* know how to open a vortex in
space-time and hack into 21st century Usenet.

don't know, you don't want to.

I think that if you are adding the digits you need an intrager rather
than an interger.

Doesn't compile on my system:

~$ gcc -Wall sumdigits.c -o sumdigits
sumdigits.c:2: warning: return type defaults to ‘int’
sumdigits.c: In function ‘main’:
sumdigits.c:4: warning: implicit declaration of function ‘printf’

Which I suppose is fine, because the OP can hardly learn anything if
you do his homework for him. Or maybe that was your point?
