Sum of digits program in C#

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:
