Read word by word from a text file in Qt4

Question

I want to read a text file word by word in Qt4 (to which I am very new to be honest), I want and write in another file one word per line. I could do this in C++ without any prob

You could combine QString::split and QStringList::join to achieve your aim:

#include <QFile>
#include <QStringList>
#include <QCoreApplication>
#include <QTextStream>

int main()
{
    QFile ifile("in.txt");
    ifile.open(QIODevice::ReadOnly | QIODevice::Text);

    // read whole content
    QString content = ifile.readAll();
    // extract words
    QStringList list = content.split(" ");

    ifile.close();

    QFile ofile("out.txt");
    ofile.open(QIODevice::WriteOnly | QIODevice::Text);

    QTextStream out(&ofile);

    // join QStringList by "\n" to write each single word in an own line
    out << list.join("\n");

    ofile.close(); 

    return 0;
}
