Original Question

If you know a vehicle's speed and the amount of time it has travelled, you can calculate the distance it has travelled as follows:

* Distance = Speed * Time

For example, if a train travels 40 miles per hour for 3 hours, the distance travelled is 120 miles. Create an application with a form of the Calculator.

When the user clicks the calculate button, the application should display an input box asking the user for the speed of the vehicle in miles-per-hour, followed by another input box asking for the amount of time, in hours, that the vehicle has travelled. Then it should use a loop to display in a list box the distance the vehicle has travelled for each hour of that time period.

ORIGINAL ANSWER:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;

namespace HW
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void calculateButton_Click(object sender, EventArgs e)
{

int count = 1;

int vehicle;

int hours;

// read text put into text boxes

if (int.TryParse(vehicleSpeedTextBox.Text, out vehicle))
{
if (int.TryParse(hoursTextBox.Text, out hours))
{

// loop number of hours displayed
while (count <= hours)
{

int distance = vehicle * count;

try
{
// write to file
//name file
StreamWriter DistanceFile;
DistanceFile = File.CreateText("Distance File.txt");

for (count = 1; count <= hours; count++)
{
distance = vehicle * count;

// convert listbox to string
outputListBox.Text = distance.ToString();
outputListBox.Items.Add("After hour " + count + " the distance is " + distance.ToString());
DistanceFile.WriteLine("After hour " + count + " the distance is " + distance.ToString());

}

DistanceFile.Close();

}
catch (Exception ex)
{

MessageBox.Show(ex.Message);

}

}
}
}
}

private void exitButton_Click(object sender, EventArgs e)
{
this.Close();
}
}
}

Modify the Distance Calculator program that you wrote before so it writes its output to a file instead of diplaying it in a ListBox control. Open the file in notepad or Visual Studio to confirm the output.
