Parallel Array in C++

In this article I would like to share with you a program that I wrote a long time ago in C++ to demonstrate the concepts of parallel array. According to Wikipedia.org, a group of parallel arrays is a data structure for representing arrays of records. It keeps a separate, homogeneous array for each field of the record, each having the same number of elements. Then, objects located at the same index in each array are implicitly the fields of a single record. Pointers from one object to another are replaced by array indices. This contrasts with the normal approach of storing all fields of each record together in memory.

If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.  People here in the Philippines who wish to contact me can reach me thru my mobile number 09173084360.

Thank you and Happy Programming.

Odd and Even Number Checker in BASH

In this article I would like to share with you a program that I wrote using BASH scripting language in Linux operating system I called this program Odd and Even Number Checker in BASH. This program is very simple and easy to understand the programs logic.

If you like my works please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. People here in the Philippine can reach me at my mobile number at 09173084360.

Thank you very much and Happy Computing.

Addition of Two Numbers in Bash

In this article I would like to share with you one of my passion in programming writing Bash Script in Linux to automate or to make simple programs under Linux operating system. This program is very simple it will ask the user to enter two numbers and then it will display the sum of the two numbers to the user.

I am using Cgywin a linux distribution operating system that enables you run linux commands under windows it is totally free to download over the Internet here is the link https://www.cygwin.com/.

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

Greeter Program in JQuery

In this article I would like to share with you a sample program that I wrote using JQuery I called this program Greeter Program what does the program will do is to ask the user to enter the first name and last name of the user and then our program will greet the user. It teaches the user how to interact with HTML and JQuery using forms and buttons.

Count Capital and Small Letters in C

In this article I would like to share with you a simple string manipulation program that I wrote using C programming language I called this program count the number of capital and small letters in c. What the program will do is to ask the user to enter a word or sentence afterwards our program will count the number of occurrence of capital and small letters in a given word or sentence by our end user. The program is very simple it users while loop statement, pointers and one dimensional array to solve the problem.

If you ask me what type of C compiler that I am using in this program I am using Dev C++ that run in CodeBlocks text editor all this compiler can download free from charge over the Internet.

I hope you will find my work useful and beneficial in your learning how to program using C programming language. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. You can reach me at my mobile number here in the Philippines at 09173084360.

Thank you very much and God Bless.

Count Capital and Small Letters in Java

While learning Java programming I came up with a problem how to count the number of occurrence of capital and small letters in a given sentence or a phrase. In this sample program I use Eclipse IDE for Java that I found very easy to use. Our program will first ask the user to enter a sentence and then our program will count how many time the capital  and small letters occurs in a given sentence.

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