Addition of Three Numbers in Java Server Pages

In this article I would like to share with you a simple program that will ask the user to give three numbers and then it will find the total sum of the three numbers using Java Server Pages or JSP. The code is very simple and easy to understand. I hope you will find my work useful thank you very much for visiting my blog.

Selection Sort in Turbo Pascal

A program that I wrote using Pascal as my programming language that will ask the user how many items to be sorted and then our program will display the original arrangement of the numbers and finally it will display the sorted arrangement of numbers on our screen. I am using selection sort algorithm to sort the given numbers by our user. I am using Turbo Pascal for Windows as my programming environment. I hope you will find my work useful. Thank you.
