Convert QString to Char*

If you went to convert prototype QString to char*,you can using this method:

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    QString str1 = "Test";

    //method 1
    strcpy(c_str2,str1.toUtf8());
 
    //method 2 
    QByteArray ba = str1.toLatin1();
    const char *c_str2 = ba.data();

    printf("str2: %s", c_str2);
    return app.exec();    
}
