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 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.
