Using % to help you.





23424 % 10 = 4


23424 / 10 = 2342


2342 % 10 = 2


2342 / 10 = 234


and so on.





Good luck, I'm also just a starter of C language learner.
Reply:int add_digits(int n)


{


int i;


int total=0;


char buffer[0xFF];


sprintf(buffer,"%d",n);


for(i=0; buffer[i]; i++)


total+=buffer[i]-'0';


return total;


}
Reply:Access the string of digits as an array. Loop through the array and convert each char to a string, the get the numeric value of the string via atoi(str) and add that to your sum.





Oh, forgot you are using c++. Use an iterator instead of an array :)
