How do i break a 5 Digit Zipcode so i can later add each digit together and get the check sum digit.

Answer 1

Assuming you read the zipcode as an integer:

int CheckSum(int zip)
{
int sum=0;
while(zip!=0)
{ sum+=zip%10; zip/=10; }
// To save the digits for later, assign
// zip%10 inside array elements.
return sum;
}
