在构造函数/析构函数中能否调用虚函数？

class Base
{
public:
    Base()
    {
        Fuction();
    }

    virtual void Fuction()
    {
        cout << " construct Base::Fuction" << endl;
    }

    ~Base()
    {
        desFuction();
    }

    virtual void desFuction()
    {
        cout << " destruct Base::Fuction" << endl;
    }
};

class A : public Base
{
public:
    A()
    {
        Fuction();
    }
    ~A()
    {
        desFuction();
    }
    virtual void Fuction()
    {
        cout << " construct A::Fuction" << endl;
    }
    virtual void desFuction()
    {
        cout << " destructr A::Fuction" << endl;
    }
};

int test()
{
    A a;                    
    return 0;
}

输出结果：

cout << " construct Base::Fuction" << endl;

cout << " construct A::Fuction" << endl;

cout << " destructr A::Fuction" << endl;

cout << " destruct Base::Fuction" << endl;
