Hi,
I'm learning C++ as a hobby using The C++ Programming Language : Special
Edition by Bjarne Stroustrup. I'm working on chpater 13 exercises that
deal with templates. Exercise 13.9 asks for me to turn a previously
made String class that deals with char's into a templated String class
that uses the template parameter C instead of char. I thought it would
be fairly simple to do this exercise, but I encoutered many errors for

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;

The spirit of this arguably pointless exercise, is that the
numeric_limits<T> class could be replaced with a totally generic
template of compile-time, template computed constants.
The problem is that it takes a *long* time to compile and the "long
double" version instantiates so many classes that gcc runs out of memory
on my 1 gig machine !
So the question is - is there a simple way to reduce the number of
template instantiations from...

Whenever I get any error with Vc++7.1/.net/2003, it is followed by huge
ammounts of "template assistance" error messaging referencing template code
(MTL) that has nothing to do with the error.
This makes it difficult to spot errors. For example, F4 to "jump to next
error" just jumps ot the next "template assistance" message. And since
there are hundreds of them, this is quite obnoxious.
Can I disable these things? Why is MSVC...

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>

Diehards,
I developed a template matrix class back around 1992 using Borland C++ 4.5
(ancestor of C++ Builder) and haven't touched it until a few days ago. I
pulled it from the freezer and thawed it out. I built a console app using
Microsoft Visual C++ 6 (VC++) and it worked great. Only one line in the
header file had to be commented out.
I built a console app using Borland C++ Builder 5. The linker complained of

Hi,
I have recently begun using templates in C++ and have found it to be
quite useful. However, hearing stories of code bloat and assorted
problems I decided to write a couple of small programs to check. What I
expected was that there would be minor code bloat and some speed
improvement when using templates. However...
I wrote a basic list container (using templates), and a list container

i'd like to implement a class template to convert binary numbers to
decimal at compile time.
and my test cases are:
BOOST_STATIC_ASSERT((bin<1111,1111,1111,1111>::value == 65535));
BOOST_STATIC_ASSERT((bin<1111>::value == 15));
BOOST_STATIC_ASSERT((bin<0>::value == 0));
BOOST_STATIC_ASSERT((bin<1010, 0011>::value == 163));

I'm currently reading Andrei Alexandrescu's book "Modern C++ Design" and
I'm a bit confused by one bit of template syntax in chapter 1.
Here is a code example:
template <class CreationPolicy>
class WidgetManager : public Creation Policy {...}
// Create an instance of WidgetManager which managers type Widget
WidgetManager< OpNewCreator<Widget MyWidgetMgr;

Overview:
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,...
