Proposed exercise
Create a function SumDigits that receives a number and returns any results in the sum of its digits. For example, if the number is 123, the sum would be 6.
Console.Write( SumDigits(123) );
6
Output
Solution
using System; public class FSumDigits { public static int SumDigits( int n ) { string number = Convert.ToString(n); int sum = 0; for (int i = 0; i < number.Length; i++) sum += Convert.ToInt32(number.Substring(i,1)); return sum; } public static void Main() { Console.WriteLine(SumDigits(123)); } }
