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.

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 Background="Red">

<Grid.RowDefinitions>

<RowDefinition Height="116*"/>

<RowDefinition Height="47*"/>

<RowDefinition Height="33*"/>

<RowDefinition Height="28*"/>

<RowDefinition Height="52*"/>

<RowDefinition Height="492*"/>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="287*"/>

<ColumnDefinition Width="141*"/>

<ColumnDefinition Width="938*"/>

</Grid.ColumnDefinitions>

<TextBlock Text="Genric Root App" Foreground="White" FontSize="25" FontFamily="Arial" Grid.Column="2" Grid.Row="1" FontWeight="ExtraBold" ></TextBlock>

<TextBlock Text="Enter Number :" Foreground="White" FontSize="15" FontFamily="Arial" Grid.Column="1" Grid.Row="2" FontWeight="ExtraBold" ></TextBlock>

<TextBox x:Name="textbox1" Grid.Row="2" Grid.Column="2" Width="200" Height="32" HorizontalAlignment="Left" VerticalAlignment="Top" ></TextBox>

<TextBlock Text="Genric Root :" Foreground="White" FontSize="15" FontFamily="Arial" Grid.Column="1" Grid.Row="3" FontWeight="ExtraBold" ></TextBlock>

<TextBlock x:Name="text1" Foreground="White" FontSize="15" FontFamily="Arial" Grid.Column="2" Grid.Row="3" FontWeight="ExtraBold" Width="200" HorizontalAlignment="Left"></TextBlock>

<Button x:Name="Button1" Grid.Column="2" Grid.Row="4" Width="122" Content="Click" Click="Button1_click" Background="Yellow" Foreground="Black" VerticalAlignment="Stretch" Margin="0,14,0,0" />

</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.
