Qsrand, srand random number generating function in qt5.15 has been discarded

  We often encounter problems such as generating random numbers , Used to be used in the past srand,qsrand Wait function is already in Qt5 The last version of Qt5.15 It's been abandoned in , here we are Qt6 Will not use it any more , In its place QRandomGenerator class .

    int x = 0, y = 0;
    srand(time(NULL));
    x = rand()%N;
    y = rand()%N;

x = QRandomGenerator::global()->generate()%N;
y = QRandomGenerator::global()->generate()%N;
