Addition of Two Numbers in JavaScript

Here is a sample program that I wrote a very long time ago while I'm teaching web programming in college. The program will ask the user to give two numbers and our program will find the sum of two numbers using JavaScript I am using HTML forms to accept values from the user. I hope you will find my work useful. Thank you.

Armstrong Number Checker in C#

Today I would like to share with you guys a program that is written by a close friend of mind, a fellow software engineer and expert C# developer Mr. Alfel Benvic G. Go he wrote this program we called Armstrong Number Checker using C#. First of all thank you Sir Bon for sharing this program to us. What does the program will do is to ask the user to give a number and then our program will compute the armstrong number based on the given number by our user. Thank you once again Sir Bon for sharing your codes to us.

String a = Convert.ToString(Console.ReadLine());

Int32 size = a.Length;

Console.WriteLine("Length of the Input Number is = " + size);

num = num / 10;

}

if (check == n)

Console.WriteLine(n + " is an Armstrong Number");

else

Pascal Triangle in C#

Today I would like to share with you guys a program that is written by a close friend of mind, a fellow software engineer and expert C# developer Mr. Alfel Benvic G. Go he wrote this program we called Pascal Triangle using C#. First of all thank you Sir Bon for sharing this program to us. What does the program will do is to ask the user to give a number and then our program will generate the corresponding pascal triangle pattern in C#. I hope you will find the work of Sir Bon useful. Thank you.
