C#:객체 Car클래스 메서드 이용하기/배열arrays(3D차원)

1. Car 객체 이용해서 Car클래스에 있는 메서드 이용하기:매개변수 이용X

//Car.cs
using System;
namespace Hello_World
{
	internal class Car
	{
		//Constructor
		public Car()
		{
			Console.WriteLine("Car was created");
		}
		public void Drive() {
			Console.WriteLine("Car is driving");
		}

		public void Stop()
		{
			Console.WriteLine("Car is stopped");
		}
	}
}

//practice.cs
using System;

namespace Hello_World
{
    class Program
    {
        static void Main(string[] args)
        {
            Car audi = new Car();
            audi.Drive();

            Console.WriteLine("press 1 to stop the car");
            string userInput = Console.ReadLine();
            if(userInput == "1")
            {
                audi.Stop();
            }
