Basic Math Operations in Perl

I love to learn many things in life programming is not an exception there are thousands of programming language around us. Each one of them has a basic application just like PHP it is design for web development, C and C++ was design to use in system programming that interact with computer hardware and peripherals. One of the programming language that caught in my attention is PERL or Practical Extraction  Reporting Language developed by Larry Wall way back in 1987 to help him in his job as system administrator.

This programming language is often called the swiss army knife in programming community because it has many application not only in console but also in web development.  My experience in Perl is very fundamentals in a sense it is my outlet from my day to day work. I found Perl easy to use and delivers result effectively however in today's IT environment most of the web application specially here in the Philippines uses PHP as their primary language by many web developers maybe because there are many frameworks like WordPress, Drupal and Joomla that is written most of the time in PHP. Again I have to emphasize I do not compare this programming languages because each one of them has a specific application.  

This sample Perl program is my first time to create a web based program using Perl as my programming language. Most of my program in Perl is written in console environment I am using XAMPP as my Perl compiler and interpreter in this sample program. What is program will do is to show the use basic mathematical operations using Perl. The basic math operations are addition, subtraction, division and multiplication. The web browser that is used to run this program is torch a similar browser like google chrome.

If you find my work useful in your programming projects and assignments please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you very much.

Addition of Three Numbers Using Perl

In this article I would like to share with you a very simple program that I wrote using Perl as my programming language. I am a beginner in terms of experience in writing codes using Perl or Practical Extraction Reporting Language.

A programming language developed by one of my favorite programmer Larry Wall way back in 1987 to help him in his system administration work before. This programming language is primarily used in server administration and web programming. What this program will do is to ask the user to enter three numbers and then our program will display the total sum of the three values early provided by our user.

Find a Number in C++

In this article I would like to share with you a simple program that I wrote using C++ as my programming language to perform linear search or sequential search in computer science data structure. I called this program find a number. What this program will do first is to ask the user to enter five integer numbers after that our program will ask the user what number to be search in a given list. If the number can be found in the list our program will tell the user which location the value is located. If the number is not in the list our program will tell the user the value to be search cannot be found in the list.

I hope you will find my program useful in you programming assignments and projects using C++ as your primary programming language. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com

Menu Program in C++

This code that I wrote in C++ is a simple menu driven program that demonstrates how to construct a menu using C++. What is good about this program is that it does not accept invalid entries there's no way our menu program will crash for invalid entries from our user. I hope this program can help other people how to make their own menu program using C++ as there programming language.
