Question

What are main difrences between * ^ and & in visual-C++ 2010?

Answer 1

^ was introduced in C++/CLI for managed objects reference, replacing the * sign used for native object pointers. So, having two types, managed and native, you need to write:

class Native
{
};

ref class Managed
{
};

Native* pn = new Native();
Managed^ pm = gcnew Managed();

& may be used to get native pointer from the native class instance. It is not used by the same way for managed classes, which are accessed only using reference.

Native n;
Native* pn = &n;
