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#.
Example
Example
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:
Output
Enter a number: 23
Sum is= 5
Example
Enter a number: 624
Sum is= 12
