A C# program to input a number and print sum of its digits.

Print the number one by one...

class Program
{

static void Main(string[] args)

{

int sum = 0,a,b;
a=int.Parse(Console.ReadLine());
for (int i = a; i > 0;i= i / 10)

{

b = i % 10;
sum = sum + b;

}

Console.WriteLine(sum);
Console.ReadLine();

}
}


For Example You type 123 it returns 6 as answer.. 1 + 2 + 3 = 6
