1、打印字符串。

2、调用简单方法，方法里有if语句、Swich语句。

using KingTest01;
using System;

namespace KingTest01

{
    class Program1
    {
        static void Main(string[] args)
        {
            Console.WriteLine("1234的千分位是" + 1234 / 1000);
            Console.WriteLine("1234的百分位是" + 1234 / 100 % 10);//12.34
            Console.WriteLine("1234的十分位是" + 1234 / 10 % 10);//123.4
            Console.WriteLine("1234的个分位是" + 1234 % 10);
            Console.WriteLine("2的10次方是" + (2 << 10));

            Program1 Test = new Program1();
            Test.year(2020);
            Test.calculate(11);
            Test.calculate1(10, 20);
            Program1 Write = new Program1();
            Write.Write();

        }

        public void year(int a)
        {
            if (a % 4 != 0)
            {
                Console.WriteLine(a + "不是闰年");
            }
            else
            {
                Console.WriteLine(a + "是闰年");
            }
        }

        public void calculate(int a)
        {
            Console.WriteLine(a + "是" + (a % 2 == 0 ? "偶数" : "奇数"));

        }
        public void calculate1(int a, int b)
        {
            Console.WriteLine(a + "和" + b + "较大的是" + (a > b ? a : b));

        }
        public void Write()
        {
            Console.WriteLine("请输入您的得分情况");

            int a = int.Parse(Console.ReadLine());//将屏幕输入的字符串转换为int类型
            switch (a / 10)
            {
                case 10:
                    Console.WriteLine("您的得分是" + a + ";非常优秀");
                    break;
                case 9:
                    Console.WriteLine("您的得分是" + a + ";优秀");
                    break;
                case 8:
                    Console.WriteLine("您的得分是" + a + ";良好");
                    break;
                case 7:
                    Console.WriteLine("您的得分是" + a + ";不错");
                    break;
                case 6:
                    Console.WriteLine("您的得分是" + a + ";一般");
                    break;
                default:
                    Console.WriteLine("您的得分是" + a + ";非常糟糕");
                    break;

            }

        }
