We can write the sum of digits program in C# language by the help of loop and mathematical operation only.

Sum of digits algorithm

To get sum of each digit by C# program, use the following algorithm:

Step 1: Get number by user
Step 2: Get the modulus/remainder of the number
Step 3: sum the remainder of the number
Step 4: Divide the number by 10
Step 5: Repeat the step 2 while number is greater than 0.

Let’s see the sum of digits program in C#.

 using System;   public class SumExample    {      public static void Main(string[] args)       {        int  n,sum=0,m;               Console.Write(“Enter a number: “);            n= int.Parse(Console.ReadLine());           while(n>0)            {             m=n%10;             sum=sum+m;             n=n/10;            }            Console.Write(“Sum is= “+sum);           }   } 

Output:

Enter a number: 23   Sum is= 5

Enter a number: 624        Sum is= 12
