fstream .eof（）循环在Xcode中工作但不是g ++

Question

嗨，我有以下循环阅读：

void personFin(vector<Person>* persvect, string filename)
{
    ifstream personfile(filename);
    string name;
    int lhstrength;
    int rhstrength;
    int erasiveskill;
    int ID = 1;
    cout << "reading in persons" << endl;
    if (personfile.good())
    {
        while (!(personfile >> name).eof())
        {
            cout << "start read in " << ID << endl;
            personfile >> lhstrength;
            personfile >> rhstrength;
            personfile >> erasiveskill;
            Person temp(name, lhstrength, rhstrength, erasiveskill, ID);
            persvect->push_back(temp);
            cout << "end read in " << ID << endl;
            ID++;
        }
        personfile.close();
    }
    else
    {
        cout << "ERROR: Cannot open file.\n";
    }
}

我在Xcode中执行了我的程序，当我使用g ++编译它时一切正常，输入文件循环是无限的

感谢您的帮助
