请将下面C#代码转成C++代码

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;

namespace BubbleSort
{
    class Program
    {
        static void Main(string[] args)
        {  string s = "";
using (StreamReader sr = new StreamReader(@"d:\file.txt"))
{
    s = sr.ReadToEnd();
    sr.Close();
}
string[] array = s.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
SortedList<int, int> list = new SortedList<int, int>();
for (int i = 0; i < array.GetLength(0); i++)
{
    if (!list.ContainsKey(Convert.ToInt32(array[i])))
    {
        list.Add(Convert.ToInt32(array[i]), Convert.ToInt32(array[i]));
    }
}
Console.WriteLine("排序前");
for (int i = 0; i < array.GetLength(0); i++)
    Console.WriteLine(array[i]);
Console.WriteLine("排序后");
for (int i = 0; i < list.Count; i++)
    Console.WriteLine(list.Keys[i]);          }


        }
    }
}
