Selecting a Value in PHP and XML

In this sample program I will show you how to select a value from a drop down menu in HTML and extract the data in an XML file. This will be my first time to write a program that uses XML and PHP. According to Wikipedia.org XML is defined as Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards.

The code is very easy to follow and understand I hope you will find my work useful in your programming projects and assignments. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

People here in the Philippines can contact me at my mobile number 09173084360.

Thank you very much and Happy Programming.

Reverse a Word in Turbo Pascal

In this article I will share a code that I wrote during my college days using Turbo Pascal I called this program reverse a word. What does this program will do is to ask the user a word or string and then it will display the word in reverse order.

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

People here in the Philippines can contact me at my mobile number 09173084360.

Thank you very much and Happy Programming.

Sample Program Output

Program Listing

Program Reverse;

Uses Crt;

Var InpStr : String;

OutStr : String;

Size, I : Integer;

Begin

Clrscr;

Write('REVERSE A WORD');

Writeln; Writeln;

Write('Please Enter A String :=> ');

Readln(InpStr);

Size := Length(InpStr);

For I := 1 To Size Do

Begin

OutStr[I] := InpStr[Size - (I - 1)];

OutStr[0] := Chr(Size);

End;

Writeln;

Write('The Reversed String is ' ,OutStr,'.');

Readln;

End.

Finding the Area of a Circle Using BASH

In this article I would like to share with you a sample program that I wrote using Bourne Again Shell or BASH scripting language that is being used in UNIX and LINUX operating system. What does the program will do is to ask the user to enter the radius of the circle and then our program will compute the area of the circle.

The script is very simple and short is very easy to understand and read. If you have some questions regarding about my works feel free to send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

People here in the Philippine who wish to contact me can reach me through my mobile number 09173084360.

Thank you very much and Happy Programming.

Sample Program Output

Program Listing

#!/bin/bash

echo -e "\n\n"

echo -e "\t\t FINDING THE AREA OF THE CIRCLE IN BASH"

echo -e "\n"

read -p "Kindly give the radius of a circle :=> " radius

echo -e "\n"

area=$(echo "scale=2;3.14159 * ($radius * $radius)" | bc)

printf "The area of the circle is %0.2f." $area

echo -e "\n"

echo -e "Thank you for using this program."

Payroll Database System in C++

In this article I will share with you a program that I wrote in C++ that will manage the payroll system of the employees in the company I called this program Payroll Database System in C++ that uses text file to save the records of the employees. In this program I am using CodeBlocks as my text editor and Dev C++ as my C++ compiler that is very available over the Internet for free because it is an open source.

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

Payroll System Using Text File in C++

One of the most interesting aspect of computer programming is how to store or save the information that we process in a text file or database for future reference. In this article I would like to share with you a program that I wrote a long time ago in my class to teach my students in C++ programming how to store the processed information in a text file in C++. The code is very straight forward and easy to understand. I hope many people will able to use this code as their basis in their learning how to program in C++.

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

Passed and Failed Grades Counter in C++

In this article I would like to share with you a program that I wrote a long time that will ask the user to enter ten grades and then our program will count how many passed and failed grades given by our user of our program. The code is very simple enough it uses one dimensional array as its basic data structure and if - else statement for conditions.

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