C++多态在派生类里的虚函数Print里调用基类里的虚函数Print（）时没有输出基类函数的返回值

这个程序运行后SalariedEmployee和CommissionEmployee重写的虚函数print调用基类的虚函数Print时没输出对象的Name和Security Number，已经用了getName函数

感觉可能是Employee定义部分的问题？

class Employee
{
private:
    string Name;
    Date Birthday;
    string Security_Number;
public:
    Employee(string name, int y, int m, int d, string num)
        :Name(name),Birthday(y,m,d), Security_Number(num)
    {}
    string getName()const
    {
        return Name;
    }
    string getSecurity_Number()const
    {
        return Security_Number;
    }
    virtual double Earning() = 0;
    virtual void Print()
    {
        cout << typeid(*this).name() << ": "<< getName() << endl;
        cout << "Birthday: ";
        Birthday.Date_Print();
        cout << "Security Number: " << getSecurity_Number() << endl;
    }
    Date getBirthday()
    {
        return Birthday;
    }

void main()
{
    vector<Employee*> employeeRef(3);
    employeeRef[0] = &SalariedEmployee("Leona", 1990, 4, 4, "11-1111-111", 800);
    employeeRef[1] = &CommisionEmployee("Kevin", 1989, 8, 1, "22-2222-222", 100000, 0.06);
    employeeRef[0]->Print();
    employeeRef[1]->Print();
}

修改如下：
employeeRef[0] = new SalariedEmployee("Leona", 1990, 4, 4, "11-1111-111", 800);
employeeRef[1] = new CommisionEmployee("Kevin", 1989, 8, 1, "22-2222-222", 100000, 0.06);

应该是最后指针赋值的时候出了问题，要用new运算符，不能直接新建一个匿名对象然后取地址，但是这是为什么呢，我发现这么做只有string类型的数据会出问题
