class foo; in header file
- by Thomas
Hi,
Is some one able to explain why header files have something like this?
class foo; // This here?
class bar
{
bar();
};
Do you need an include statement when using this?
Thanks.

However, the simple test I built seems to indicate that this is not behaving as I had expected/hoped. Is there a way to setup my classes in such a way that…Read the article
