    Default Read with one thread, send datas to another thread

    Im working with threads. In the following code, i read datas from txt and run it on my thread. I want to use another thread for writing the datas another txt file. How can i do it?

    mythread.cpp


    Qt Code:
    1. #include "mythread.h"
    2. #include <QtCore>
    3. #include <QDebug>
    4. #include <QFile>
    5. MyThread::MyThread()
    6. {
    7.  
    8. }
    9.  
    10. void MyThread::run() //Reading file from txt with thread1
    11. {
    12. QFile file("C:/Users/ilknu/Documents/untitled1/deneme.txt");
    13.  
    14. if (file.open(QIODevice::ReadOnly))
    15. {
    16. QTextStream in (&file);
    17. while (!in.atEnd())
    18. {
    19.  
    20. QString line = in.readLine();
    21. QStringList list = line.split(QLatin1Char(' '), Qt::SkipEmptyParts);
    22. for(const QString &entry : list)
    23. {
    24. double num = entry.toDouble();
    25. qDebug()<<num;
    26. queue.enqueue(num);
    27.  
    28. } // for
    29. } // while
    30. } // if
    31.  
    32. file.close();
    33. }
    To copy to clipboard, switch view to plain text mode

    There is no reason to use threads for this. Open both files, read from one file, compute your sum, and write it to the second file. When the reading file is at the end, close both files.

    Maybe his toolbox is filled only with hammers, so every problem becomes a nail.
