Convert QStringList to multiple integers

samy03

I have a QStringList like ["2", "3", "4"] and I'm trying to compare numbers in this QStringList to a QString which only has one number in it.

QStringList list = ["2", "3", "4"];
QString number = "3";

for (int i=0 ; i<3 ; i++)
{
           if (number == list.at(i))
           {
                 //do something
           }
          else
          {
            //do something else 
          }
}

I am not able to make it work. What am I doing wrong?

Any suggestions will be greatly appreciated.
Thank you

Hi,

What exactly is not working ?

On a side note, why not use a QVector<int> rather than a QStringList of numbers ?

You should also rather write your for loop based on your container rather than use fixed values:

for (const QString& value : list) {
    if (value == "3") {
        // Do something 
    } else {
        // Do other something 
    }
}

It acts like if true condition was not met.

Even with your code its doing the same thing.

This works fine:

#include <QtDebug>
#include <QStringList>

int main(int argc, char *argv[])
{
    Q_UNUSED(argc);
    Q_UNUSED(argv);

    QStringList list{"1", "2", "3"};
    for (const QString& value : list) {
        if (value == QStringLiteral("3")) {
            // Do something
            qDebug() << "Found";
        } else {
            // Do other something
            qDebug() << "Nop" << value;
        }
    }
    return 0;
}
