在 C++ 里，如果我想让派生类的析构函数在释放内存时被调用，我得在基类中将其声明为虚拟函数。那么在 Visual Studio 2005 中，对于某个派生类来说，即使它在基类中未被声明为虚拟的，其析构也会被调用吗？-In C++ years, if I want a derived class destructor is called when the memory is released, I need to declare it as a base class virtual function. Then in Visual Studio 2005, for a derived class, even if it is not declared in the base class is virtual, its destructor will be called you?
