冒泡排序：int temp = 0; Console.WriteLine(请输入元素的个数); int count = int.Parse(Console.ReadLine(); int arr = new intcount; for (int i = 0; i arr.Length; i+) Console.WriteLine(请输入第0个值, i + 1); arri =int.Parse( Console.ReadLine() ); for (int i= 0; i arr.Length - 1;i+) for (int j = 0; j arrj+1) / 交换元素 temp = arrj; arrj = arrj+1; arrj+1 = temp; for (int i = 0; i c & a + c b & b + c a) if (a * a + b * b = c * c | a * a + c * c = b * b | b * b + c * c = a * a) Console.WriteLine(可以构成直角三角形); else Console.WriteLine(可以构成三角形，但不能构成直角三角形); else Console.WriteLine(不能构1成三角形); Console.ReadLine();定义一个类：person.csusing System;using System.Collections.Generic;using System.Text;namespace Con class person public string name;/1.写成员变量。2.构造函数(先写无参构造函数)。3.写属性。 int age;/4.写方法。5.方法的重载。6.实名化对象 public string sex; public int Age/属性 get return age; set if (value 0 & value 40) return 老人; else return 青年; public string compare(int a) if (this.age a) return 比他大; else return 比他小; public static void compare(person a, person b) if (a.age b.age) Console.WriteLine( + + 大); else Console.WriteLine( + +大); Program.csusing System;using System.Collections.Generic;using System.Text;using Con;/命名空间不同，用using 组织。namespace ConsoleApplication1 class Program static void Main(string args) person zhang = new person(张,女); zhang.Age = 50; person li = new person(李,男); li.Age = 20; zhang.sayHI(); li.sayHI(); Console.WriteLine( + +pare(); Console.WriteLine( + + pare(); Consol
