Answer to Question #256009 in C# for Umar farouk

Question

Sum the digits in an integer) Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14. Hint: Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 / 10 = 93.

            int n = -1;


            while (n < 0 || n > 1000)
            {
                Console.Write("Enter an integer between 0 and 1000: ");
                n = int.Parse(Console.ReadLine());
            }


            int sum = 0;


            while (n != 0)
            {
                sum = sum + n % 10;
                n = n / 10;
            }
            Console.WriteLine("The sum of the digits is : {0}", sum.ToString());


            Console.ReadLine();
        }
