More Classes

Here are the classes we did for the evening session.

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MultiClassExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Display dis = new Display();
            //Mileage m = new Mileage();


            //m.BeginningMiles = 1000;
            //m.EndingMiles = 1450;
            //m.Gallons = 25;
            //m.PricePerGallon = 3.71;

            //Console.WriteLine("Your miles per gallon are {0:F2}", m.MilesPerGallon());
            //Console.WriteLine("The cost per Mile is {0:C}", m.CostPerMile());

            //Mileage m3 = new Mileage(2000, 2400);
            //m3.Gallons = 20;
            //Console.WriteLine("The MPG is {0}", m3.MilesPerGallon());


            //Mileage m2 = new Mileage(12000, 12500, 25);
            //Console.WriteLine("The MPG is {0}", m2.MilesPerGallon());

            //Console.ReadKey();
        }
    }

    //I could write a new class right here
}
