memory management for

[scottrm]

I am quite new to C++ on .Net and have a question with regard to memory
managent. Is a class which is NOT prefixed with _gc created on the heap
or stack. Also are there any other things I have to bear in mind when working
with such a class as opposed to working with a pre .Net C++ class.

A class that isn't declared __gc is an unmanaged C++ class, so it can live
on the stack or the heap depending on how you define your variables, e.g.

struct X {};

void g(const X&);

void f()
{
X x; // On the stack
X* p = new X; // On the (unmanaged) heap
delete p; // Must remember to delete p - should use smart pointer
g(X()); // This creates a temporary X, which lives on the stack
}
Also are there any other things I have to bear in mind when working
with such a class as opposed to working with a pre .Net C++ class.

Not that I know of.
