I have a class that contains a nested class. The outer class is called
outer, and the nested class is called inner. When I try to compile the
following code, I get a number of errors. It is not obvious to me, where
I'm going wrong (the compiler messages do not seem to make much sense).
here is the code:
outer class declared as ff in "outer.h":
#include "inner.h"
class outer {
public:
outer() ;
~outer() ;
private:
class inner ;
inner m_inner ;
public:
void dothis(void){ m_inner.dothis( ) ; }
void dothat(void){ m_inner.dothat( ) ; }
};
inner class declared as follows in "inner.h" :
#include "outer.h"
class outer::inner {
friend class outer ;
outer::inner() ;
~outer::inner() ;
void dothis( void ) {} ;
void dothat( void ){} ;
}
Here is main() function:
#include "outer.h"
#include "inner.h"
int main(int argc, char* argv[]) {
outer y ;
y.dothis() ;
y.dothat() ;
}
I will be very grateful for advice to help me fix this as I spent a
large portion of yesterday trying to fix this by reffering to various
documentation - none of ehich actually addresses the issue of using or
delegating to a nested class as I'm trying to do above. MTIA 2 1139
Hmmm, inner.h includes outer.h and outer.h includes inner.h <-- a dumb
compiler would go into an infinite loop - a smart one would tell you that
you cannot do that.

I think you can do it like this....
class outer {
public:
outer() ;
~outer() ;
private:
class inner {
friend class outer;
inner();
~inner();
void dothis( void ) {} ;
void dothat( void ){} ;
} m_inner;
public:
void dothis(void){ m_inner.dothis( ) ; }
void dothat(void){ m_inner.dothat( ) ; }
};

Hi All,
I remember reading that both nested classes and namespaces would be
available in PHP5. I know that namespaces got canceled (much sadness...),
however, I *thought* that nested classes were still an option.
However, I am coming up dry looking for information on how to do this, and
the most recent references I am able to find to nested classes in PHP are
dated 2003. And they all say the same thing: sorry, can't do that.

I'm trying to find an example of a nested class implemented within the .NET

Many thanks!

Hi all,
I'm wondering if you how you organize as (in sorting / order) your C# class code:
Do you sort/ group by member type: fields, methods, properties etc.?
If yes: what ordering scheme do yo use?
Do you group members by visibility - and how does that relate to grouping by type?
Where do you insert (nested) types such as enums and delegates in classes

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
