C++在文本文件中升序排列數字

所以我寫了一個小老虎機程序，但我不能爲我的生活弄清楚如何排序這些數字。C++在文本文件中升序排列數字

我把它寫出來生成一個文件的隨機數，但我需要他們按升序排序。我還需要進行二分搜索以搜索文件中的值，但我現在只是擔心排序問題。這裏是我有什麼幫助，非常感謝！

它寫出在虛空SlotMachine文件:: spinReel（）

請發佈一個自包含的示例代碼片段。沒有人想要閱讀100多行代碼。 – MoRe

如果你希望所有的nnumbers進行排序，你可以使用矢量

#include <vector> //at the top

....

vector<int> vAlls; 

    srand(time(NULL)); 

    for (i = 0; i < 3; i++) 
    { 
     for (j = 0; j < 3; j++) 
     { 
      reels[i][j] = rand() % LIMIT + 1; 
      ////// write out to file ///// 
      ofstream outputFile("project.txt", ios_base::app); 
       outputFile << reels[i][j]<<"\n"; 
       outputFile.close(); 

      vAlls.push_back(reels[i][j]); 
    //else cout << "Unable to open file"; 
     } 
    } 

    sort(vAlls.begin(),vAlls.end());

此矢量排序方式。這是否回答你的問題？

這不是它寫在project.txt文件中排序... 有沒有辦法，我可以把它放在別的地方，它打開它並對它進行排序然後關閉它？ – iEpic

我向你展示瞭如何檢索所有內容並將其排列在向量中。您可以自己完成其他任務（將矢量的內容放入文件中） – Gabriel
