編程課后實驗

1、1. 設計一個windows應用程序，輸入一個正整數，逆序打印出每一個位數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() Ini

2、tializeComponent(); 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;

3、 textBox2.Text = b.ToString(); 2. 設計一個簡單的windows應用程序，輸入聯(lián)系人的姓名，電話和email，單擊“添加”按鈕，顯示聯(lián)系人的相應信息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

4、 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："

5、+ ab.Name + "n" + "電話：" + ab.Phone + "n" + "Email：" + ab.Email + "n" private void button2_Click(object sender, EventArgs e) textBox1.Text = "" textBox2.Text = "" textBox3.Text = "" textBox1.Focus(); 3. 自定義一個時間類。該類包含小時，分，

6、秒字段與屬性，具有將秒增加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();

7、 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(); t

8、extBox3.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

9、= t.Minute.ToString(); textBox3.Text = t.Second.ToString(); 4. 設計一個windows應用程序，在該程序中首先構造一個學生基本類，再分別構造小學生，中學生，大學生等派生類，當輸入相關數據，單擊不同按鈕（小學生，中學生，大學生）將分別創(chuàng)建不同的學生對象，并輸入當前的學生總人數，該學生的姓名，學生類型和平均成績using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;us

10、ing 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 chi

11、nese = double.Parse( textBox3.Text ); double math = double.Parse( textBox4.Text ); Pupil stu = new Pupil(name,age,chinese,math); label6.Text += "總人數：" + Student.number + "," + "姓名：" + stu.Name + "," + "小學生,平均成績?yōu)椋?quot; + stu.Average() + "n" priv

12、ate 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,

13、english); label6.Text += "總人數：" + Student.number + "," + "姓名：" + stu.Name + "," + "中學生,平均成績?yōu)椋?quot; + 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 xuanxiu = double.Parse(textBox4.Text); University stu =
