Program Listing

#include <iostream>

using namespace std;

struct num {

     int value[3];

 };

int addition(num a)

 {

     return(a.value[0] +

            a.value[1] +

            a.value[2]);

 }

 main() {

        num b;

        cout << "\t Sum of Three Numbers ";

        cout << "\n\n";

        cout << "Enter three numbers : ";

        cin >> b.value[0] >> b.value[1] >> b.value[2];

        cout << "\n\n";

        cout << "The sum is "  <<addition(b);

        cout << "\n\n";

Product Total Cost in C++

A simple program that I wrote in C++ that will compute the product total cost. I used this program as an example in my programming class in college before I work in the industry as software engineer. I hope you will find my work useful.

Currency Converter in C++

In this article I would like to share with you a sample program that I wrote 6 years ago in my class in C++ programming I called this program currency converter in C++. I will ask the user amount of money in US dollars and then it will convert into Philippine Peso equivalent using structure as my data structure in C++. I hope you will find my work useful in learning C++ programming.

Compare Two Strings in Java

In this article I would like to share with you a sample program that I wrote in Java to compare the two string if they are the same or the first string is greater than the second string or vice versa. One of the things that I love in Java is that there are many built in functions that makes programming much easier compared to other programming language. I hope you will find my work useful.

Sample Program Output

Program Listing

Compare_String.java

package hello;

import java.util.Scanner;

public class Compare_String {

public static void main(String args[]) {

String str1, str2;

Scanner input = new Scanner(System.in);

System.out.println("Compare Two String in Java");

System.out.println();

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

str1 = input.nextLine();

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

str2 = input.nextLine();

if (str1.compareTo(str2) > 0)

{

System.out.println();

System.out.println("The first string is greater than the second string.");

}

else if (str1.compareTo(str2) < 0)

{

System.out.println();

System.out.println("The first string is smaller than the second string.");

}

else 

{

System.out.println();

System.out.println("Both Strings are equal.");

}

System.out.println();

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

Alert Dialog Box in Android

When I started learning how to create an application in Android I came across of idea to add quit button which allows our user to quit the program within our application in this article I will complete the functionality of our application Sum and Product Program in Android. I will added the alert or quit dialog box that will ask the user if the user want to quit or return to our program. The code is very simple and easy to understand I enjoy every moment of it working with this simple application program in Android I hope you will find my work useful too.
