指定数字排序

 lab :

            Console.WriteLine("比较5个数字的大小");
            Console.WriteLine("请输入第一个数字：");
            int n1 =Convert.ToInt32( Console.ReadLine());

            Console.WriteLine("请输入第二个数字：");
            int n2 = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine("请输入第三个数字：");
            int n3 = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine("请输入第四个数字：");
            int n4 = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine("请输入第五个数字：");
            int n5 = Convert.ToInt32(Console.ReadLine());
            int[] a = new int[5] { n1,n2,n3,n4,n5};

            int temp;
           
            //外循环           
            for (int outer = 4; outer >= 1; outer--)
            {
                for (int inner = 0; inner <= outer - 1; inner++)
                {

                        a[inner]=a[inner+1];
                        a[inner + 1] = temp;
                    }
                }

            }
            Console.WriteLine("排序后的结果是：");
            for (int i = 0; i <= 4; i++)
