var 声明局部变量

//程序员笑话 ： http://news.mydrivers.com/1/407/407317.htm

 

然后课堂练习（我一个蹭课的写什么课堂练习啊。。。）

1.字符提取，整数整除练习

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace BitAdd{    class Program    {        static void Main(string[] args)        {            String s;            s = Console.ReadLine();            Method1(s);            Method2(s);        }        private static int Method2(String s)        {            int sum = 0, i = 0;            int t = int.Parse(s);            int []b = new int[100];            Console.Write("实现思路2：每一位的值为：");            while (t > 0)            {                b[i++] = t % 10;                sum += t % 10;                t /= 10;            }            for (int r = i- 1; r >= 0; r--)                Console.Write(b[r] + "、");            Console.WriteLine(" 这些位之和为" + sum);            return sum;        }        private static int Method1(String s)        {            int sum = 0;            Console.Write("实现思路1：每一位的值为：");            for (int i = 0; i < s.Length; i++)            {                Console.Write((Convert.ToInt32(s[i]) - 48) + "、");                sum += Convert.ToInt32(s[i] - 48);            }            Console.WriteLine(" 这些位之和为" + sum);            return sum;        }    }}

2. 5个整数的正序与倒序

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Array{    class Program    {        static void Main(string[] args)        {            int[] n = new int[5];            string[] temp = new string[5];            string s = Console.ReadLine() ;            temp = s.Split(‘,‘);            for (int i = 0; i < 5; i++)                n[i] = int.Parse(temp[i]);            for(int i = 0; i < 5; i++)                for(int r = 0; r < i; r++)                    if (n[i] > n[r])                    {                        int tt = n[i];                        n[i] = n[r];                        n[r] = tt;                    }            Console.Write("正序:");            for (int i = 4; i >= 0; i--)                Console.Write(n[i] + " ");            Console.WriteLine();            Console.Write("倒序:");            for (int i = 0; i < 5; i++)                Console.Write(n[i] + " ");            Console.WriteLine();                  }    }}

3.简易计算器（Windows） ..待补充
