[C#]冒泡排序

数组类测试环境与排序算法

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

namespace Data_structure_and_algorithm
{
    class CArray
    { private int[] arr; private int upper; private int numElements; public CArray(int size) 
        {
            arr =new int[size];
            upper = size - 1;
            numElements = 0;
        } public void Insert(int item) 
        {
            arr[numElements] = item;
            numElements++;
        } public void DisplayElements() 
        { for (int i = 0; i <= upper; i++) 
            {
                Console.Write(arr[i]+" ");
            }
            Console.WriteLine();
        } public void Clear()

校验排序过程与结果

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Data_structure_and_algorithm { class Program { static void Main(string[] args)
        {
            BubbleSort();
        } public static void BubbleSort()
        {
            CArray nums = new CArray(10);
            Random rnd = new Random(100); for (int i = 0; i < 10; i++)
            {
                nums.Insert(rnd.Next(0,100));
            }
            Console.WriteLine("Before sorting:");
            nums.DisplayElements();
            Console.WriteLine("During sorting:");
            nums.BubbleSort();
            Console.WriteLine("After sorting:");
            nums.DisplayElements();
            Console.ReadKey();
        }

    }
