How to sort a QStringList by random

[sonichy]

I am writing a program of poker game, and I store a pack of 52 cards in QStringList.
How to shuffle the QStringList by random ?

QStringList poker;
for(int i=1;i<14;i++){
    QString s = "diamond" + QString::number(i);
    poker << s;
}
for(int i=1;i<14;i++){
    QString s = "spade" + QString::number(i);
    poker << s;
}
for(int i=1;i<14;i++){
    QString s = "heart" + QString::number(i);
    poker << s;
}
for(int i=1;i<14;i++){
    QString s = "club" + QString::number(i);
    poker << s;
}
for(int i=1;i<3;i++){
    QString s = "joker" + QString::number(i);
    poker << s;
}
qDebug() << poker;
// ("diamond1", "diamond2", "diamond3", "diamond4", "diamond5", "diamond6", "diamond7", "diamond8", "diamond9", "diamond10", "diamond11", "diamond12", "diamond13", "spade1", "spade2", "spade3", "spade4", "spade5", "spade6", "spade7", "spade8", "spade9", "spade10", "spade11", "spade12", "spade13", "heart1", "heart2", "heart3", "heart4", "heart5", "heart6", "heart7", "heart8", "heart9", "heart10", "heart11", "heart12", "heart13", "club1", "club2", "club3", "club4", "club5", "club6", "club7", "club8", "club9", "club10", "club11", "club12", "club13", "joker1", "joker2")

Hi,

std::shuffle might be what you want.

@SGaist OK！

std::random_device rd;
std::mt19937 g(rd());
std::shuffle(poker.begin(), poker.end(), g);
