C#期末复习实验题.doc

实验2-3 结果 55int i = 5, j = 5, p, q, s; p = (i+) + (i+) + (i+); q = (+j) + (+j) + (+j); int t = 0; s = i + t + j + t + p + t + q; Console.WriteLine(s);实验2-4 结果：False False int x, y; bool z1, z2; x = 1; y = 0; z1 = (x 1) & (+y 0); z2 = (x 1) & (+y 0); Console.WriteLine(0,1,z1,z2); 结果：8,8,10 int x = 10, y = 9, a, b, c; a = (-x = y+) ? -x : +y; b = x+; c = y; Console.WriteLine(0,1,2, a, b, c);实验3-1 编程：由键盘输入3个整数a，b，c，输出其中最小的数。 int a, b, c; Console.Write(输入三个整数:); a = Convert.ToInt32(Console.ReadLine(); b = Convert.ToInt32(Console.ReadLine(); c= Convert.ToInt32(Console.ReadLine(); if (a b & a c) Console.WriteLine(a); else if (b a & b = a & a = A & a = 0 & a = 0 & ch = a & ch = A & ch = Z) n2+; else if (ch = ) n3+; ch = (Char)Console.Read(); Console.WriteLine(数字： + n1 + 字母： + n2 + 空格： + n3);实验4-4 编写一程序求出所有的水仙花数。水仙花数是指一个3位数，其各位数字的立方和恰好等于该数本身。例如，153=1*1*1+5*5*5+3*3*3，所以153是水仙花数。 int i, a,b,c,sum; for (i = 100; i 1000; i+) a = i / 100; b = (i - a * 100) / 10; c = i % 10; sum = a * a * a + b * b * b + c * c * c; if (i = sum) Console.WriteLine(水仙花数是：0, i); 实验5-4 设计一个windows应用程序，界面如下图所示，连续输入一串数字，然后进行从小到大排序。 public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) string str = textBox1.Text; string strs = str.Split(,); int a = new int10; for (int i = 0; i strs.Length; i+) ai = Convert.ToInt32(strsi); Array.Sort(a); for (int i = 0; i 9; i+) label3.Text = label3.Text + ai + ,; label3.Text = label3.Text + a9; 实验6-2 有一3*3 矩阵，求出两条对角线元素值之和；int, score; int i, j, sum; score = new int3, 3; for (i = 0; i 3; i+) for (j = 0; j 3; j+) scorei, j = int.Parse(Console.ReadLine(); for (i = 0; i 3; i+) for (j = 0; j 3; j+) Console.Write(0,4:d, scorei, j); Console.WriteLine(); sum = score0, 0 + score1, 1 + score2, 2 + score2, 0 + score0, 2; Console.WriteLine(对角线元素之和为0, sum); Console.Read();实验7-1 在c#中编写一个控制台应用程序，要求实现以下功能：设计一个Retangle类，提供通过length和width字段计算面积和周长的两个方法，并用 main方法来测试程序。Retangl r = new Retangl(4, 5); Console.WriteLine(周长为： + r.getL(); Console.WriteLine(面积为： + r.getS(); class Retangl double s, l; public Retangl(double w, double h) s = w * h; l = 2 * (w + h); public double getL() return l; public double getS() return s; P256 第二题class Program static void Main(string args) int sn, x, ss; double cc, yc, sc; string name; Console.WriteLine(请输入有几个学生); sn = Convert.ToInt32(Console.ReadLine(); Student a = new Studentsn; for (int i = 0; i sn; i+) Console.WriteLine(请输入学生姓名：); name = Convert.ToString(Console.ReadLine(); Console.WriteLine(请输入学生学号：); x = Convert.ToInt32(Console.ReadLine(); Console.WriteLine(请输入学生C+成绩：); cc = Convert.ToDouble(Console.ReadLine(); Console.WriteLine(请输入学生英语成绩：); yc = Convert.ToDouble(Console.ReadLine(); Console.WriteLine(请输入学生数学成绩：); sc = Convert.ToDouble(Console.ReadLine(); Student s = new Student(name, x, cc, yc, sc); ai = s; for (int j = 0; j sn; j+) Console.WriteLine(aj); for (int j = 0; j sn; j+) Console.WriteLine(aj.toString(); Student temp ; for (int i = 0; i sn - 1; i+) for (int j = 0; j aj + 1.getArrage() temp = aj; aj = aj + 1; aj + 1 = temp; for (int j = 0; j sn; j+) Console.WriteLine(aj.toString2(); P256 第五题class Program static void Main(string args) CPerson cp = new CPerson(aaa,101,m); CStudent cs = new CStudent(bbb, 102, f, 98); CTeacher ct = new CTeacher(ccc, 103, f, 54); Console.WriteLine(cp); Console.WriteLine(cs); Console.WriteLine(ct); Console.ReadKey(); class CPerson public string name,sex;
