C#上机实验题目和答案.pdf

1、创建一个控制台应用程序，要求用事件每 10 秒报告机器的当前时间。 2、编写一个掷筛子 100 次的程序，并打印出各种点数的出现次数。 3、兔子繁殖问题。设有一对新生的兔子，从第三个月开始他们每个月都生一对 兔子，新生的兔子从第三个月开始又每个月生一对兔子。按此规律，并假定兔子 没有死亡，20 个月后共有多少个兔子？要求编写为控制台应用程序。 1. using System; using System.Threading; namespace ConsoleApplication1 class michael public void TimerHandlerA(object obj, EventArgs e)/ Event handler Console.WriteLine(DateTime.Now.ToString(); class Program static void Main() michael m = new michael(); MyTimerClass mc = new MyTimerClass(); mc.Elapsed += m.TimerHandlerA; Thread.Sleep(30000); public class MyTimerClass public event EventHandler Elapsed; private void OnOneSecond(object a, EventArgs i) if (Elapsed != null) Elapsed(a, i); private System.Timers.Timer MyPrivateTimer; public MyTimerClass() MyPrivateTimer = new System.Timers.Timer(); MyPrivateTimer.Elapsed += OnOneSecond; MyPrivateTimer.Interval = 10000; MyPrivateTimer.Enabled = true; 2. using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication2 class Program static void Main(string args) int a = 0, b = 0, c = 0, d = 0, e = 0, f = 0; System.Random rnd = new System.Random(); for (int i = 1; i = 300 | label1.Top = 300) this.label1.Left = 0; this.label1.Top = 0; 运行结果: （4） using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace WindowsApplication4 public partial class Form1 : Form private string s = “; private string t = “; int a, b, c; private string r = “; public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) s += button1.Text.ToString(); textBox1.Text = s; private void button2_Click(object sender, EventArgs e) s += button2.Text.ToString(); textBox1.Text = s; private void button3_Click(object sender, EventArgs e) s += button3.Text.ToString(); textBox1.Text = s; private void button4_Click(object sender, EventArgs e) s += button4.Text.ToString(); textBox1.Text = s; private void button5_Click(object sender, EventArgs e) s += button5.Text.ToString(); textBox1.Text = s; private void button6_Click(object sender, EventArgs e) s += button6.Text.ToString(); textBox1.Text = s; private void button7_Click(object sender, EventArgs e) s += button7.Text.ToString(); textBox1.Text = s; private void button8_Click(object sender, EventArgs e) s += button8.Text.ToString(); textBox1.Text = s; private void button9_Click(object sender, EventArgs e) s += button9.Text.ToString(); textBox1.Text = s; private void button15_Click(object sender, EventArgs e) s += button15.Text.ToString(); textBox1.Text = s; private void button14_Click(object sender, EventArgs e) r = button11.Text.ToString(); textBox1.Text = r; b = Convert.ToInt32(s); s = “; if (t = “+“) c = a + b; else if (t = “-“) c = a - b; else if (t = “*“) c = a * b; else if (t = “/“) c = a / b; textBox1.Text = c.ToString(); private void button10_Click(object sender, EventArgs e) t = button10.Text.ToString(); textBox1.Text = t; a = Convert.ToInt32(s); s = “; private void button12_Click(object sender, EventArgs e) t = button12.Text.ToString(); textBox1.Text = t; a = Convert.ToInt32(s); s = “; private void button11_Click(object sender, EventArgs e) t = button11.Text.ToString(); textBox1.Text = t; a = Convert.ToInt32(s); s = “; private void button13_Click(object sender,
