Write a C# program that reads an integer from keyboard and computes and displays the sum of digits of that integer.

For example, if the input is 256, your program display: The sum of digits for 256 is 13 (since 2 + 5 + 6 = 13 as we know).

Run your program with 4 different input data: 256, 2014, a 5 digit number picked by you, and an 8 digit number picked by you.
