C# Program using Functions

Program Statement:

Write a function which takes one value as parameter and display the sum of digits in the value. e.g. if user has passed 125 then function will print 1+2+5 = 7

Solution:

 class _sum
 {
 long n, i, sum = 0;
 public void add(long n)
 {
 for (i = n; i != 0; i = i / 10)
 {
 sum = sum + i % 10;

 }
 Console.WriteLine(" Sum of digits is : {0}", sum);
 }
 public void input()
 {
 Console.Write(" Enter desired digit : ");
 n = Convert.ToInt64(System.Console.ReadLine());
 add(n);
 }

 }
