In this program we will see how to sum the digits of a given number.
E.g: If
user enters number as 1234 then the output will be 1+2+3+4=9.
Program:
class SumOfDigitsProgram
{
public static void Main()
{
int sum = 0;
Console.WriteLine(" /********** Program to sum of Digits ************/");
Console.Write("Enter a number:");
int number = int.Parse(Console.ReadLine());
int tempnumber = number;
while (tempnumber > 0)
{
sum += (tempnumber % 10); // adds last digit of tempnumber to sum
tempnumber /= 10; // divides tempnumber by 10 to cuts the last digit
}
Console.Write("Sum of {0} digit is {1}",number,sum);
Console.Read();
}
}Output:
Note: If you want to give number beyond the int range, change the data type of input value(number).
