Hi all,
I am having a problem trying to overload a function template, based on
a typedef, such as:
template<class T>
struct A
{};
template<class T>

Although I've got over most of my template-related problems, I'm
having trouble when I started to use default template parameters.
For template type T, I've typedef'd this as object_type and then
typedef'd std::vector<T> menu_list. This doesn't seem to
work though:
40 template<typename W>
41 class ObjectOptionMenuDescribeObject

Hello Experts!
I have the following Array template class see below.
I execute these three statements
statement 1: Array<int> x(5);
statement 2: cin >>x;
statement 3: Array<int>::element_type y = x;
but I can't understand the last one which is
Array<int>::element_type y = x;
We have a typedef T element_type; in the template Array class see below

I have the following sample program, which can convert function object
with 1 argument into function object with 2 arguments. It can also do +
between function object of the same type.
The last line is very long. I'm wondering if there is any way to
suppress it. I can only think of typedef. But I'm not sure whether I
can use typedef for the return type.
Would you please help me? Please don't be daunted by the length of the
code.

Hello NG,
sorry to bother again, but I am a lit surprised that I got no answer on my
post (attached below).
So I refined the code a little bit :-).
If there is a typedefed class X inside a class Y which has the same typedef
name and used in the form "Instance_Y::type::type" MSVC7.1 fails to compile.
See example below.

Hello people,
I am getting errors from VS2003 when working with typedef'ed types.
For example, assume that I have a type T, defined in a 3rd party include file based on some condition
#if (condition)
typedef char T;
#else
typedef short T;

I am trying to simulate typedef template similar to the suggestion of
Herb Sutter in the following article: http://www.gotw.ca/gotw/079.htm
However when implementing typedef templates according to his
suggestion, I run into type inference problems when passing typedef
templates as arguments to template functions. It seems the compiler
(gcc 4.0) cannot resolve the typedef template with an instantiation of
that typedef template. Below is...

Hi,
I don't think I can't do this directly with standard C++, I've tried all
the ways I could think of that make sense and then some. I was wondering
if someone had a genius idea how I could produce behavior, using
standard C++, akin to what I guess can be best called a "typedef
specializations".
I.e. this being the default:

Hello all. I have a simple question that seems trivial but I can't
make it to work. I have a class that takes as a template argument,
another class. The idea is as follows:
#include <iostream>
using namespace std;
template <class ClassB>
class ClassA

Hi everyone,
Yet another syntax problem that's baffling me with templates. I want to
instantiate a template with a single parameter as per normal, however
the parameter is actually a template class itself, with all *its*
parameters filled out (in the form of a typedef.) I can't work out how
to break apart the typedef to reveal what data types were used to create
it in the first place.
Here is some example code that demonstrates the...

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...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
