Hello Everybody

I would greately appreciate if Somebody could tell me how to calculate Sum of each position of an integer in C like if there is 123 then it should give 1+2+3=6 and similary if it is 1237838 then it should give 1+2+3+7+8+3+8=32

Thank you.

Dave

CPP / C++ / C Code:

// num = number whose digits are to be totalled
 
sum = 0;
 
while( num != 0 ) 
{
    sum += num % 10;
    num /= 10;
}
