Sum of digits of a number in .NET using for loop

In this program we will see how to sum the digits of a given number using for loop.

E.g: If user enters number as 123456 then the output will be 1+2+3+4+5+6=21

Program:

namespace DotNetMirror
{
    class SumofDigitsUsingForLoop
    {
        public static void Main()
        {
            int sum = 0;
            Console.WriteLine(" /********** Program to sum of digits using for loop ************/");
            Console.Write("Enter a number:");
            int number = int.Parse(Console.ReadLine()); int tempNumber = number ;
            for (; number != 0; number = number / 10)
            {
                sum += (number % 10);
            }
            Console.Write("Sum of {0} digit is {1}", tempNumber, sum);
            Console.Read();
        }
    }
}

Output:

/********** Program to sum of digits using for loop ************/

Enter a number:123456

Sum of 12346 digit is 21

Note: If you want to give number beyond the int range, change the data type of input value (number).
