8.Polymorphism object in container (C沒有) 若要將多型的object放進container,則一定得用pointer,因為reference不能copy,這寫是C++與C#差異很大的地方。 繼續上一個多型的程式,現在我們想將這些多型的object放進vector內。 1 /* 3 4 Filename :Polymorphism.cpp ...

Yes you can, and in C++ it looks something like: auto ptr = reinterpret_cast<ptr_type>(0x0012FF7C); Where ptr_type is a valid pointer type, like int* for example. To add a bit more clarity to the problem outlined in the lesson: Memory addresses are constantly being reclaimed ...
