Addition and Subtraction of Two Numbers in JavaScript

Hi there thank you for visiting my website I have a very busy week in my work that why I was not able to update my blog anyway moving forward. In this sample program will show you how to add and subtract two numbers using HTML forms in JavaScript. The code is very easy to understand for beginners that are new in JavaScript. I hope you will find my work useful.

OOP Payroll System in C++

A simple object oriented payroll system that I wrote in C++ before that I would like to share to my fellow programmers, students and persons who likes programming. I hope you will find my work useful.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com

My mobile number here in the Philippines is 09173084360.

Program Listing

#include <iostream>

#include <iomanip>

using namespace std;

class payroll {

private:

string name;

int days_work;

float rate;

float solve;

public :

int get_info();

void display_info();

};

int payroll :: get_info()

{

cout << "\t\t Simple Payroll System Using OOP in C++";

cout << "\n\n";

cout << "Enter Employees Name : ";

getline(cin,name);

cout << "Enter No. of Days Worked : ";

cin >> days_work;

cout << "Enter Daily Rate : ";

cin >> rate;

cout << fixed << setprecision(2);

solve = (days_work * rate);

}

void payroll ::display_info()

{

cout << "\n\n";

cout << "==== DETAILED REPORT =====";

cout << "\n\n";

cout << "\nEmployees Name : " << name;

cout << "\nEmployees Salay is : $" << solve;

cout << "\n\n";

system("pause");

}

main() {

payroll emp;

emp.get_info();

emp.display_info();

}

Odd and Even Numbers in C++ using Structure

A simple program that I wrote a long time ago that will check if the give number is odd or even using structure in C++.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com

My mobile number here in the Philippines is 09173084360.

Program Listing

#include <iostream>

#include <iomanip>

using namespace std;

struct odd {

int n;

int odd_even() {

if (n % 2 == 0)

{

cout << n <<" Number is even!\n";

}

else

{

cout << n << " Number is odd!\n";

}

return(n);

}

};

main() {

odd value;

cout << "\t\t ODD and Even Number Determiner";

cout << "\n\n";

cout << "Enter a Number :";

cin >> value.n;

cout << "\n\n";

cout << value.odd_even();

cout << "\n\n";

Addition of Two Numbers Using Spring Framework

I am very new in Java Enterprise Edition or J2EE programming particularly using Spring Framework. But I find it easy to learn once you have known the basic concepts and principles behind it. I am thankful that there is a video tutorial in YouTube that we can study to be specific the tutorial of Ankush Gorav here his website http://www.gontu.org.

I have learned a lot from his tutorial in YouTube. In gives me an idea how to get started this sample program that I wrote is based on his tutorial will ask the user to give two numbers and then our program will find the total sum of the two numbers.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com

My mobile number here in the Philippines is 09173084360.

Scanner in = new Scanner(System.in);

System.out.println();

System.out.println("Addition of Two Numbers");

System.out.println("\n");

System.out.print("Enter First Value : ");

a = in.nextInt();

System.out.print("Enter Second Value : ");

b = in.nextInt();

sum=(a+b);

System.out.println("\n");

System.out.print("The sum of " + a + " and " + b + " is " + sum +".");

System.out.println("\n");

System.out.println("End of Program");

Sample Program Output

Program Listing

Public Class Form1

Private Sub Find_Palindrome(ByVal strString As String)

Dim str As String

str = StrReverse(UCase(strString))

If str.Equals(UCase(strString)) Then

Label2.Text = UCase(strString) + " is a Palindrome."

Else

Label2.Text = UCase(strString) + " is Not a Palindrome."

End If

End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Factorial Solver in Visual Basic .NET

A factorial program that I wrote using Microsoft Visual Basic .NET to solve for the factorial of the number. The code is very easy to understand I create a function called factorial which uses recursion algorithm to solve the factorial of the given number by our user.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com

My mobile number here in the Philippines is 09173084360.

Sample Program Output

Public Class Form1

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Label2.Visible = False

End Sub

Private Function Factorial(ByVal inputval As Integer) As Integer

Dim f As Integer

Factorial = 1

For f = 2 To inputval

Factorial = Factorial * f

End Function

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Label2.Visible = True

Dim myNumber1, mynumber2 As Integer

myNumber1 = Val(TextBox1.Text)

mynumber2 = Factorial(Val(TextBox1.Text))

Label2.Text = "The factorial value of " & myNumber1 & _

" is " & mynumber2 & "."
