Dear all,
I have a question about default template parameters.
I want to have a second template parameter which as a default parameter,
but depends on the first one (see below). Is something like that possible?
Some workaround?
Thank you,
Patrick

Hi all,
I was working with a simple function template to find the min of two values.
But since I would like the two values to be different (type) I dont know
what kind of value (type) it will return. I tried to write something like
this:
template <class Type1, class Type2, class Type3>
Type3 findMin(Type1 x, Type2 y){
return (x < y) ? x : y;

I'm fine tuning a scope_handle class that takes a policy class as the
second template.
http://code.axter.com/scope_handle.h
Please see above link for full understanding of the problem.
One thing I don't like about the way the current policy template is
setup is that for the ptr_policy class the first template type is
different from the template type given to the policy.
And on the other policy classes, the template type is the same....

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 there,
I am playing around with template metaprograming: I am trying to
redefines my own types. But I am facing a small issue, where I cannot
describe the whole implementation in one single class. Instead I have
to separate implementation for binary and ascii in two different
classes as I don't know how to use the traits technique for
constructors.
Any pointers very welcome !

Hello,
I'm having some difficulty compiling template classes as containers for
other template objects. Specifically, I have a hierarchy of template
classes that contain each other. Template class B has an instance of
template class A, which has some base type T (usually int or double).
However, the base type T is important to calculations in B, so I would
like to obtain access to the type for further variable declaration
within B. ...

Hi everyone. A very simple question. I would like to know what is
better in terms of performance. I want to use a simple function to
obtain the minimum of two values. One way could be using a macro:
#define min(a,b) ((a<b)?a:b)
I thought that another way could be to use a template function:
template <class T>
T min<T a, T b>

Hi everyone,
The idea is quite simple: generate a container with random values in
it. For that, I decided to create a class that I called
RandomContainer that inherits from a container (with default value
std::vector<T>). To handle the different ways that the values are
randomized, I created a traits class. The problem that I have, is that
the function randomize() within the traits class takes different
parameters depending on the type...

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,...
