The following code fails to compile. My intention is to provide
different definitions for a nested class for a class template partial
specialization. Here it is:
template <typename , int class Outer {
public:
class Inner;
};
template <int iclass Outer<int, i>::Inner {};
template <int iclass Outer<double, i>::Inner {};
Do you have any idea why?
Thanks.

The rule is, "you cannot specialise the member of a class template
without first specialising the template".

Don't quite get it. I am able to specialize a member function without
specializing the entire class template. The code below compiles OK:
template <typename struct F {
void f();
};
template <>
void F<int>::f() {};
template <>
void F<double>::f() {};
I thought I could do the same with an inner class. If not, I would use
some indirection to achieve the effect I want. Redefining the inner
class would have been more direct.

I believe you're confusing full specialisation with partial. A full
specialisation is *not* a template. A partial specialisation is still
a template. Try specialising your F::f for, say, all pointers.

Now I get it. I was mixing them up. Thanks. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I'm planning to create a macro-based property system (reflection,

should somehow know ThisClass, and that's where it start to get tricky.
A #define ThisClass would of course help, but I'd rather make it part

The code below does not compile under g++.
There is an outer class template that contains and inner class
template. The outer class template is fully specialized for int. Then
a separate Foo class template inherits from the inner.
The compiler indicates that the inner class is incomplete when used as
the base class of the inner class template. Why?

For example, like in the following, the part commented out was
intended as partial spectialzation, but it would even compile. Is it

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
