Accessing text file contents



  • Hi,
    I am reading a text file by using the following code

    QFile inputFile("cotdr.txt");
    inputFile.open(QIODevice::ReadOnly);
    QTextStream in(&inputFile);
    QString line = in.readAll();
    inputFile.close();

    the text file contains the numbers like
    6789,1234,4567,7890,9845
    4567,7890,1234,4523,6789
    3467,4304,2411,1111,2321

    now I want to compare 6789 & 4567 and keep the maximum number(6789) and compare the kept number(6789) with 3467 and return the maximum number of each row
    finally I have to get an output file with maximum numbers 6789,7890,4567,7890,9845 also viceversa

    could some one please suggest me how could I do that?
    an example code helps me a lot using c++
    please hope someone knows about how to do that, i am eager to see the reply
    thanks heaps



  • @ while (!file.atEnd()) {
    QByteArray line = file.readLine();
    QList<QByteArray> numbers = line.split(',')
    for(QString numstr:numbers)
    {
    int num = numstr.toInt();
    .....
    }
    }@



  • Thanks for your reply, but when i complied it says doesn't support for loop in cpp.

    alos.i have one more question is there any possibility that i can setup qbytearray line as a two dimensional array

    how can compare when i have line numbers indexed with rows in qlist
    i need to compare the columns
