    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; }

    please do not ask people to do your entire homework for you
    I never asked anyone to do my complete homework.

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

    No, but that's what you were hoping for "I always get my boring homework done by others"

    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!
