How to read specific word from a Text file in Qt ?

Pappu Kumar Keshari

From a text file I have to read only 3.2 from 3rd (version) line how can I read ?
My Text file contains : ->
File : 123
IP : 192.67.7.45
version : 3.2
Latest : 3.4.6
when I am using this code then it is showing output as -> "version : 3.2" But I need only 3.2 as a output

QFile file("C:/Users/PAPPU KUMAR KESHARI/OneDrive/Desktop/Pappu123.txt");
if (!file.open(QFile::ReadOnly | QFile::Text)) {
QMessageBox::warning(this,"title","file not open");
}

QTextStream in(&file);
QString text;
while (!in.atEnd()) {
    text = in.readLine();
    if (text.contains("version"))
       break;
}
qDebug() << text;
file.close();

Please suggest me and need any improvement in my code then please do it .

Take a look at the split() functions of QString and also the search functions.

Why should I write code for you? You know when the string contains version so use this string and split it up...
