编程课后实验

1. 设计一个windows应用程序，输入一个正整数，逆序打印出每一个位数using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) textBox1.Text = ; textBox2.Text = ; textBox1.Focus(); private void button2_Click(object sender, EventArgs e) int a = int.Parse(textBox1.Text); int b = 0; while (a 0) b = b * 10 + a % 10; a = a / 10; textBox2.Text = b.ToString(); 2. 设计一个简单的windows应用程序，输入联系人的姓名，电话和email，单击“添加”按钮，显示联系人的相应信息using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) string name = textBox1.Text; string phone = textBox2.Text; string email = textBox3.Text; AddressBook ab = new AddressBook(name,phone,email); label4.Text += 姓名： + ab.Name + n + 电话： + ab.Phone + n + Email： + ab.Email + n; private void button2_Click(object sender, EventArgs e) textBox1.Text = ; textBox2.Text = ; textBox3.Text = ; textBox1.Focus(); 3. 自定义一个时间类。该类包含小时，分，秒字段与属性，具有将秒增加1秒的方法using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) int hour = int.Parse(textBox1.Text); int minute = int.Parse(textBox2.Text); int second = int.Parse(textBox3.Text); Time t = new Time(hour, minute, second); t.AddSecond(); textBox1.Text = t.Hour.ToString(); textBox2.Text = t.Minute.ToString(); textBox3.Text = t.Second.ToString(); private void button2_Click(object sender, EventArgs e) textBox1.Text = ; textBox2.Text = ; textBox3.Text = ; private void Form1_Load(object sender, EventArgs e) Time t = new Time(); textBox1.Text = t.Hour.ToString(); textBox2.Text = t.Minute.ToString(); textBox3.Text = t.Second.ToString(); 4. 设计一个windows应用程序，在该程序中首先构造一个学生基本类，再分别构造小学生，中学生，大学生等派生类，当输入相关数据，单击不同按钮（小学生，中学生，大学生）将分别创建不同的学生对象，并输入当前的学生总人数，该学生的姓名，学生类型和平均成绩using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) String name = textBox1.Text; int age = int.Parse( textBox2.Text ); double chinese = double.Parse( textBox3.Text ); double math = double.Parse( textBox4.Text ); Pupil stu = new Pupil(name,age,chinese,math); label6.Text += 总人数： + Student.number + , + 姓名： + stu.Name + , + 小学生,平均成绩为： + stu.Average() + n; private void button2_Click(object sender, EventArgs e) String name = textBox1.Text; int age = int.Parse(textBox2.Text); double chinese = double.Parse(textBox3.Text); double math = double.Parse(textBox4.Text); double english = double.Parse(textBox5.Text); Middle stu = new Middle(name, age, chinese, math,english); label6.Text += 总人数： + Student.number + , + 姓名： + stu.Name + , + 中学生,平均成绩为： + stu.Average() + n; private void button3_Click(object sender, EventArgs e) String name = textBox1.Text; int age = int.Parse(textBox2.Text); double bixiu = double.Parse(textBox3.Text); double xuan
