《实时控制软件设计》第二周作业

停车场门禁系统状态机：

                                                  

代码如下：

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

namespace qichemenjin
{
    /// <summary>
    /// 判断起降杆状态
    /// </summary>
    class LiftLever
    {
        public bool llstate;
        public LiftLever()
        {
            llstate = false;
        }
       
        
        public void Showllstate()
        {
            if (llstate == true)
                Console.WriteLine("起落杆升");
            else
                Console.WriteLine("起落杆降");
        }
    }
    /// <summary>
    /// 判断等的状态
    /// </summary>
    class TrafficLight
    {
        public bool tlstate;
        public TrafficLight()
        {
            tlstate = false;
        }
       
        
        public void Showtlstate()
        {
            if (tlstate == true)
                Console.WriteLine("绿灯亮");
            else
                Console.WriteLine("红灯亮");
        }
    }
    /// <summary>
    /// 判断车的状态
    /// </summary>
    class Car
    {
        public bool carstate;
        public Car()
        {
            carstate = false;
        }
        public void Showcarstate()
        {
            if (carstate == true)
                Console.WriteLine("有车入闸");
            else
                Console.WriteLine("车已出闸");
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Car car = new Car();
            LiftLever lever = new LiftLever();
            TrafficLight light = new TrafficLight();
            car.Showcarstate();
            lever.Showllstate();
            light.Showtlstate();            
            while (car.carstate=true)
            {
                Console.WriteLine("是否有车入闸（y/n）");
                var input = Console.Read();
                if(input=='y')
                {
                    car.carstate = true;
                    car.Showcarstate();
                    lever.llstate = true;
                    lever.Showllstate();
                    light.tlstate = true;
                    light.Showtlstate();
                    Console.Read();
                }
                else
                {
                    Console.WriteLine("车已出闸");
                    Console.WriteLine("起落杆降");
                    Console.WriteLine("红灯亮");
                    
                    Console.Read();
                }
                Console.Read();
            }           
        }
    }
}

运行结果如下：
