Methods Morning Class

Here is the Morning class's sample code for methods. It is a little different from the evening class. I did not comment it nearly as thoroughly

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

namespace Methods
{
    class Program
    {
        static void Main(string[] args)
        {
            Program prog = new Program();
            prog.Display();
            prog.PauseIt();
        }//end of Main

       private void PauseIt()
        {
            Console.WriteLine("Press any key to exit");
            Console.ReadKey();
        }//end of PauseIt

       private void Display()
       {
           Console.WriteLine("Enter the beginning mileage");
           double beginningMileage = double.Parse(Console.ReadLine());

           Console.WriteLine("Enter the ending mileage");
           double endingMileage = double.Parse(Console.ReadLine());

           double miles = TotalMiles(beginningMileage, endingMileage);

           Console.WriteLine("\nYour total miles is {0}",miles);

           Console.WriteLine("Enter the number of Gallons");
           double gallons=double.Parse(Console.ReadLine());

           double milesPerGal = MilesPerGallon(miles, gallons);
           Console.WriteLine("Your miles per gallon is {0}", milesPerGal);
           
       }//end Display

       private double TotalMiles(double startMiles, double endMiles )
       {
           return endMiles - startMiles;
       }//Total Miles

       private double MilesPerGallon(double totalMiles, double gals)
       {
           double mpg = totalMiles / gals;
           return mpg;
       }//end MilesPerGallon

    }//end of program class

}//end of namespace
