Thread: How do I add the digits of a number ?

Code:

int num =5648;

How do i get 5+6+4+8 easily ?

How to get all the digits separately in different variables and then add them ?

By "easily" I mean without using special functions.

Code:

while (n) { sum += n%10; n /= 10; }

Thanks! Cboard is a great place to get homework done.

Duh!
That was your home work?

If you wanted to reverse a positive number? You are welcome!

I never asked anyone to do my complete homework.

I just asked for a hint. What can I do if someone comes and writes the piece of code ?



Anyway, sorry. (I don't want to argue any more)

Sorry

you are welcome abk. next time, just PM me. i will do your home work. $0.5 per line of code.

manav, you should write your code so then

Code:

while (n)
{
   sum += n%10;
   n /= 10;
}

no, like this:

Code:

while (n)
{
  d = n%10;
  sum += d;
  n /= 10; 
}

$3.0 please!

Code:

while (n)
{
  d = n%10;
  sum += d;
  n /= 10; 
}
