Find Out Generic Root of Number in Windows Store App

Introduction

In this article I will describe generic roots. So let us first of all understand them. They are the sum of the digits of a number unit; we don't get a single digit.

For example: 456 = 4+5+6 = 15 and since 15 is two digits, 1 + 5 = 6.

Therefore the generic root of 456 = 6.

Now I will create the generic root logic in Windows Store app.

Step 1

First of all you have to create a new Windows Store Application.

Open Visual Studio 2012
"File" -> "New" -> "Project..."
Choose "Template" -> "Visual C#" -> "Window Store app"
Choose "Blank App (XAML)" then rename the application

Step 2

Write the following XAML code in "Mainpage.Xaml" (that is available in Solution Explorer):

<Page

x:Class="genric_root_app.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="using:genric_root_app"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d">

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</Grid>

</Page>

Step 3

Now write the following C# code for the button within "Mainpage.Xaml.cs".

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;

using Windows.UI.Xaml.Data;

using Windows.UI.Xaml.Input;

using Windows.UI.Xaml.Media;

using Windows.UI.Xaml.Navigation;

namespace genric_root_app

{

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

protected override void OnNavigatedTo(NavigationEventArgs e)

{

}

private void Button1_click(object sender, RoutedEventArgs e)

{

int num = 0, sum=0, r;

num = Convert.ToInt32(textbox1.Text);

while (num >= 10)

{

sum = 0;

while (num > 0)

{

r = num % 10;

num = num / 10;

sum += r;

}

if (sum >= 10)

{

num = sum;

}

else

break;

}

text1.Text = sum.ToString();

}

Step 4

Run your app.
