Posted by Satya Prakash Articles | Windows Store Apps January 30, 2013
In this article I will explain how to find out Sum of Digit to Entered Number in Windows Store App.
  • 0
  • 0
  • 4591

In this article I explain how to separate each digit of a number and then add each digit and show the sum of each digit. So I will first seperate each digit, then add them.

Use the following procedure to do that.

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"
  • "Blank App (XAML)", then rename the application

Step 2

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

<Page

    x:Class="sum_of_each_digit_entered_number.MainPage"

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

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

    xmlns:local="using:sum_of_each_digit_entered_number"

    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.ColumnDefinitions>

            <ColumnDefinition Width="461*"/>

            <ColumnDefinition Width="905*"/>

        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions>

            <RowDefinition Height="122*"/>

            <RowDefinition Height="39*"/>

           

            <RowDefinition Height="33*"/>

           

            <RowDefinition Height="37*"/>

            <RowDefinition Height="537*"/>

        </Grid.RowDefinitions>

        <TextBlock Text="Sum of Each Digit of Entered Number" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Foreground="White" Grid.Column="1" Grid.Row="1"/>

        <TextBlock Text="Enter number" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Foreground="White" Grid.Column="0" Grid.Row="2" TextAlignment="Right"></TextBlock>

        <TextBox x:Name="textbox1" Grid.Column="1" Grid.Row="2" Width="140" Height="32" HorizontalAlignment="Left" VerticalAlignment="Top" />

        <Button x:Name="button1" Content="Click" Click="button1_Click" Grid.Column="1" Grid.Row="3" Background="Yellow" Foreground="Black" Width="118" Height="38" VerticalAlignment="Top" Grid.RowSpan="2" />

        <TextBlock x:Name="text1" Grid.Column="1" Grid.Row="4" TextWrapping="Wrap" Width="219"  HorizontalAlignment="Left" Margin="0,6,0,497" FontSize="15" FontWeight="ExtraBold" />

    </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 sum_of_each_digit_entered_number

{

    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, r, sum = 0;

            num = Convert.ToInt32(textbox1.Text);

            while (num > 0)

            {

                r = num % 10;

                num = num / 10;

                sum = sum + r;

            }

            text1.Text = sum.ToString();

        }

    }

}

 

Step 4

Now Run your app.
