Decimal To Roman Numeral in JQuery

A program that I wrote using JQuery that will ask the user to enter a decimal number and then it will convert into a roman numeral format. The code is very simple and easy to understand JQuery is one of the most popular Javascript framework library that is widely used by many web developers around the world.

var list_numbers=[1, 4, 5, 9, 10, 40, 50, 90, 100, 400, 500, 900, 1000];

var x = parseInt(val);

if( x<1 || x>4999 )

alert(x+' number is out of range.');

return 0;

}

display_result = '';

for(a=12; a>=0;)

if( list_numbers[a]<=x )

{

display_result += roman_numerals[a];

x -= list_numbers[a];

}

else

{

a--;

}

return(display_result);

value_number = parseInt(prompt("Enter a number"));

document.write("<h3>"+value_number + " is equivalent to " +

convert_to_roman(value_number) + " in roman numerals. </h3>");

Find the highest in three numbers in Jquery

I wrote this program to practice my knowledge about JQuery a very popular javascript framework that makes JavaScript programming much easier and enjoyable. What does the program will do is to ask the user to enter three numbers and then the program determine and display which of the three numbers is the highest. I hope you will find my work useful in learning how to write a program in JQuery.

User Manager Login System in Visual Basic 6

In this article I would like to share a work of my best friend Dave Marcellana a user manager login system written in Visual Basic 6. I ask Dave if he would like to share some of his work in Visual Basic 6 here is it an initial installment one of his program. This program will protect your application from unauthorized access by intruders and other users. I hope you like the work of Dave use this code in your Visual Basic 6 applications and projects freely.

List of Employee's using Two Dimensional Array in Java

While I'm learning Java programming one of the most important data structure to be studied by every programmings is array. Array refers to a list of values belong with the same data type. There are several kinds of array in Java the first one is one dimensional array, two dimensional and multi dimensional arrays. In this article I would like to show you two dimensional array in Java that will list down the name's of the employee's. The program code is very short and very easy to understand by beginner's in Java programming. I hope you will find my work useful in your programming projects and assignments.

Daily Time Record Form HTML and CSS

This will be the first time in my website that I push a work that is not related on computer programming rather than more on user interface I called this design layout daily time record form using HTML and CSS in this example I based my layout in Civil Service Form 48 a standard daily time record form used by government employees here in the Philippines. I hope this short article can help others in understanding how to design and create their our web layouts using HTML and CSS.

Payroll System Using Structure in C++

I this article I would like to share with you guys a sample program that I wrote a long time ago in my C++ programming class in college using structure as our data structure. I called this program payroll system that will compute the salary of an employee in the company. To give you some idea structure is also known as records in other programming language such as Pascal it can contains several variables and different data type but still belong with the same entity.

If you have some questions please send me an email at jake.r.pomperada@gmail.com and jakerpomperada@yahoo.com. My mobile number here in the Philippines is 09173084360.

Program Listing

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

struct employee {

string name, department;

int age;

char gender;

float days, rate;

};

main() {

float solve=0.00;

string sex;

employee user;

cout << "\t\t XYZ Payroll Solver 1.0";

cout << "\n\n";

cout << "\t Created By: Mr. Jake R. Pomperada, MAED-IT";

cout << "Enter the Name of the Employee : ";

getline(cin,user.name);

user.gender = getchar();

cout << "Enter the Number of Days Worked : ";

cin >> user.days;

cout << "Enter the Daily Rate : ";

cin >> user.rate;

solve = (user.days * user.rate);

if (user.gender == 'M' || user.gender == 'm')

}

else if (user.gender == 'F' || user.gender == 'f')
