获取mac地址
#include <QCoreApplication>
#include <QNetworkInterface>
#include <QDebug>int main(int argc, char *argv[])
{QCoreApplication a(argc, argv);// 获取所有网络接口的列表QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();// 遍历每个网络接口for (const QNetworkInterface &interface : interfaces) {// 获取接口的 MAC 地址QString macAddress = interface.hardwareAddress();if (!macAddress.isEmpty()) {qDebug() << "Interface:" << interface.humanReadableName();qDebug() << "MAC Address:" << macAddress;}}return a.exec();
}
c++ 随机数
#include <QCoreApplication>
#include <QDebug>
#include <random>
#include <QString>QString generateRandomNumberString()
{std::random_device rd; // 用于获取随机种子std::mt19937 gen(rd()); // 使用 Mersenne Twister 生成随机数std::uniform_int_distribution<> dis(10000000, 99999999); // 生成 8 位随机数int randomNumber = dis(gen);return QString::number(randomNumber);
}int main(int argc, char *argv[])
{QCoreApplication a(argc, argv);QString randomNumberString = generateRandomNumberString();qDebug() << "Generated 8-digit random number string:" << randomNumberString;return a.exec();
