C#上手练习1（if语句、Swich语句）

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;

            }

        }
    }
