Centimeter To Feet Converter in JavaScript

This program that I wrote in JavaScript will convert the height of the person from centimeter to feet. I'm using HTML as my markup language and JavaScript to perform as series of computation and conversion of values from centimeter to feet. I hope you will find my work useful in your programming projects and assignments using JavaScript.

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

Thank you very much.

Compound Interest Solver in JavaScript

One of my favorite scripting programming language is JavaScript in this program I wrote a simple Compound Interest Solver that will solve for the interest rate for the loan made by the person. The code is very simple and easy to understand, I'm using notepad++ as my test editor in writing this program.

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

Thank you very much.

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.

Fahrenheit To Celsius Solver in Bash

In this article I would like to share with you a sample program that I wrote using BASH scripting language or Bourne Again Shell in Linux operating system I called this program Fahrenheit To Celsius Solver in Bash. What the program will do when the user run the script using ./fah.sh or bash fah.sh it will ask the user to enter the temperature in Fahrenheit and the program will convert it to its Celsius equivalent.

The script is very short and very easy to understand a good way to automate some math problems using Bash as our programming language under the Linux environment. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

Prime Number Checker in Bash

I'm still learning how to program in Bash or Bourne Again Script that is very useful in system administration in Unix or Linux operating system. There is already some improvements in my understanding how to create different types of script using Bash. Indeed learning Bash scripting programming is a wonderful journey that everyone that is interested will truly enjoy.

In this article I would like to share with you a simple script that will check if the given number by the user is a prime number or not. First thing we must able to understand what is really a prime number. A prime number an be divided evenly only by 1, or itself. And it must be a whole number greater than 1 there are many examples of  prime number one example is 3 that can divided evenly by 1 and itself the same with 5,7,11,13,17,19 and so on and so forth. An example of number that is not a prime number is 8 that is very divisible by 2,4.

I hope you will find my sample bash script useful in your learning bash programming. If you have some questions feel free to send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

Thank you very much.

Leap Year Checker in Bash

In this article I would like to share with you a simple bash script that I wrote to check if the given year by the user is a leap year or not a leap year. In order for us to understand leap year occurs every four years just like the Olympic games examples of leap year are 1988, 2000, 2004, 2008 and etc. 

The formula in bash script in checking for leap year is a=$(($year % 4)) in this expression we assign a variable a to check if the given year that is being stored in variable year has a remainder of 4. The operator we use to check of remainder is % also known as modulo. If assignment operator a is equal to without any remainder in the given year that year will become a leap year. In addition our script will allow the user to repeat the program running by asking the user if the user would like to run the program again or not. What is good about this script it checks if the response of the user to run the program is valid or not valid it makes our script more secure in accepting only valid response from our user.

I hope you will find our program useful in your learning how to write bash script in Linux and Unix operating system. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

Thank you very much.

Even and Odd Number Checker in Bash

In this article I would like to share with you a simple program that uses BASH or Bourne Again Shell in Linux operating system I called this program Odd and Even number Checker.  What this program will do is to ask the user to enter a number and then the program will check and determine if the number odd or even number. What is good about this program is that after the program determine the number whether it is even or odd number. The program will ask the user to continue using the program or not if the user choose y for yes the program will run again, if no the program will terminate and will return to command line.

If hope you will find my work useful in learning how to program using Bash scripting language in Linux, Unix or others distributions. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

Addition of Five Numbers in Bash

One of the interesting aspects of open source software is that we can explore different types of tools and programming languages that can help us in our everyday work. When I started learning Linux way back in 2010 I can say it is a different experience first time in my life I was able to learn an operating system that is free, open source, stable and best of all has many built in functions that cannot be found in windows operating system. At first I found myself in a difficult situation because of lacking of experience in Linux and there are only few books written on that particular subjects. The biggest hindrance for beginners like me how to learn the rules in using Linux in everyday computing activities.

The best advice that I get actually is the forum that I read in the Internet the journey in Linux or Unix operating system is a step by step process. Read a lot from blogs, tutorials and articles in the Internet and do some example activities in your computer by installing virtual machine or install the full installation of the operating in your computer. It takes a lot of courage and confidence to learn something new in this ever changing world of Information Technology. By persistence, hard work and patience your effort spend in learning Linux is a worth while.

In this article I would like to share with you my avid reader of my blog of the simplest script that I have written using BASH script of Bourne Again Shell I called this program addition of five numbers. What the program will do is to ask the user to enter five numbers and then it will compute for the sum of five numbers being given by our user. I am using Ubuntu 14.04 as my Linux distribution, I try to improve myself in the aspect of scripting programming using BASH because it is very useful in system administration of networks.

If you find my work useful let me know kindly send me an email at jakerpomperada@yahoo. com and jakerpomperada@gmail.com.

Thank you very much.

Password Security in C++

One of the basic protection that we can apply in our computer is the use of password. In this article I will show you a sample program that I wrote before a simple password security program in C++. What this program will do is to ask the user to enter the correct password as you run the program, every time the user type the password it display asterisk character to hide the real password underneath it protects the user from anyone who looks in their screen while they are typing for this password to access their system.

I hope you will find my work useful in your quest in learning C++ as your programming language.

Thank you very much.

Lower Case To Upper Case Conversion in C++

This program that I wrote will show you how to convert lowercase words in a given sentence into uppercase equivalent using C++ as my programming language. The C++ library file that I used to convert lowercase into uppercase is #include <cctype> this library file has a built in function called toupper() that enables the programmer to convert lowercase characters into uppercase characters. I hope you will find my work useful and beneficial in your learning how to program in C++.

Thank you very much.

Vowel Omitter in C++

In this article I would like to share with you a sample program that I wrote a long time ago in my class in C++ programming I called this program Vowel Omitter. What this program will do is to ask the user to enter a sentence and then the program will remove or omit all the vowels that can be found in the words in the given sentence. I used this program to show my students in my class that C++ has many features that are suitable in string manipulation not just solving numbers.

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

Thank you very much.

Positive and Negative Numbers Counter in C++

One of the basic programming problems that I have developed for my C++ programming class here in the Philippines is to count the number of positive and negative numbers being given by the user of our program. My intention of creating this program is to introduce my students in my programming class how to understand and learn how to use one dimensional array as their data structure to display the positive and negative numbers in our program.

Normally arrays is one of the simplest data structure in my own opinion that can be learned easy by apply person interested in computer programming. We can define array as a list of values that has the same data type and having the same variable name also. It is very easy to manage data if we are using arrays because we are only dealing with one variable name but we can identify different values in our array by its index or elements that we access in our program. 

If order for us to determine if the number is positive is by having using this condition in our program  if (numbers[y] >=0) this condition tells us the if number[x] is greater the zero then it will display all positive numbers in our program. In our case I consider zero as positive number in our example. For checking for negative numbers and display the values of our screen I am using this condition if (numbers[y] < 0) this condition implies that if the given numbers by our user is less that zero then the values to be displayed will be negative numbers.

I hope you will find my sample program beneficial and useful in your learning how to use arrays as your data structure in your C++ program. If you have some questions about my work please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you very much.

Prime Number Checker in Python

In mathematics we refer a number that is a prime number if the number is greater than one  that has no positive dividend or divisor other than 1 and itself.  For example 7 is considered as prime number primarily because 1 and 7 are its only it positive integer factors, whereas 8 is composite because it has the divisor of 2 and 4.

I wrote this program using Python as my programming language if your find my work useful in your programming assignments and projects using Python you can send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you very much.
