C#上机实验题目和答案7.doc

（1） 创建一个控制台应用程序，在该程序中定义一个School类，该类中有一个私有的整型数组grade,用来存储学生的成绩，还有一个公共的整型索引器，用来读写grade数组中的各元素，该类中还有一个公共的构造函数，给grade数组初始化为有10个元素。在Program类的Main()方法中声明一个School类实例，然后利用索引来对grade数组中的元素进行赋值和显示。（2） 创建一个控制台应用程序，在程序中定义一个性别枚举类型，性别枚举类型只有两个元素：female和male。再定义一个学生结构类型，其中包括学号、姓名、性别、年龄字段，其中学号、姓名为字符串类型，性别为枚举类型，年龄为整型。在Main方法中声明一个学生结构类型的变量，给它的各个成员赋值，然后以字符串的形式输出它的各个成员的值。（3） 创建一个控制台应用程序，从10个整数中找出最大数和次大数。5.实验数据记录及分析（或程序及运行结果）1. using System;using System.Collections.Generic;using System.Text;namespace ConsoleApplication1 class School private int grade; public int thisint index set if (index = 0 & index = 0 & index 10) return gradeindex; else return 0; public School() grade = new int10; class Program static void Main(string args) School Sgrade = new School(); Sgrade0 = 60; Sgrade1 = 70; Sgrade3 = 80; Sgrade5 = 90; Sgrade7 = 99; Sgrade9 = 59; for (int i = 0; i 10; i+) Console.WriteLine(同学0成绩为1, i, Sgradei); 2.using System;using System.Collections.Generic;using System.Text;namespace ConsoleApplication2 enum Sex female, male struct Student public string name; public string number; public int age; public Sex sex; class Program static void Main(string args) Student a1 = new Student(); Student a2 = new Student(); = a1; a1.number = 106700; a1.age = 20; a1.sex = Sex.female; = a2; a2.number = 106701; a2.age = 21; a2.sex = Sex.male; Console.WriteLine(name=0,number=1,age=2,Sex=3, , a1.number, a1.age, a1.sex); Console.WriteLine(name=0,number=1,age=2,Sex=3, , a2.number, a2.age, a2.sex); 3.using System;using System.Collections.Generic;using System.Text;namespace ConsoleApplication3 public class BubbleSorter public void sort(int list) int i, j, temp; bool done = false; j = 1; while (j list.Length) & (!done) done = true; for (i = 0; i listi + 1) done = false; temp = listi; listi = listi + 1; listi + 1 = temp; j+; class Program static void Main(string args) int array = new int 111, 12,21, 43, 5, 6, 87, 45,85, 38 ; BubbleSorter Max = new Bubb
