Bubble 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 bubble 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.

I am currently accepting programming work kindly contact me in the following email address for further details. Thank you.
