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

Zodiac Sign Checker in PHP

This code is being given to us by my friend named Alfredo Soliva an IT student here in the Philippines in their programming class in PHP and MySQL programming. I am very happy that some programmers and students visiting my website and sharing their codes to help our fellow programmers and software engineers.

What that program will do is to ask the user to select form the combo box the month and day and then the program will check what zodiac sign belongs the user of our program. The code uses also some JavaScript for form validations and CSS for the design of the webpage. I hope the work of our friend Alfredo gives you an idea how to program in PHP.

Celsius To Fahrenheit Solver in Bash

This is another conversion of temperature that I wrote using Bash script. In my previous article I wrote a program that will ask the user to enter the temperature in Fahrenheit and then it will convert to its Celsius temperature equivalent. By this time it another way around from Celsius it will convert to its Fahrenheit value.

Take note in my sample bash program I always adding some functionalities like asking the user if the user wants again to run the program so that it can give a different value and then give us the different converted values. It makes our bash script more versatile in many ways. I hope you will find my sample bash script programs more useful in your learning how to program in bash in UNIX, MAC OS and Linux environment.

If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

Thank you very much.
