     A simple program that I wrote using Delphi as my programming language that will ask the user to give a number and then our program will check and determine whether the given number from the user is a positive or negative number. The code is very short and very easy to understand. Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
