Need info on Template specialisation

I have a question regarding template specialisation.

Assume I have a generic template class

template <class S, class T>

class A{

void f() {

// Some code here

}

}

I want to specialise the function f() for say A<int, S>.

Do I need to specialise the entire class.

If else how do i specialise just this fn/?

You mean for A<int,T>?

Yes, you do.

You cannot. No partial specialisations of function templates are allowed.
A simple way would be to overload 'f' in the class.

No,if you want to explicitly specialize the function:

template<>
void A<int,float>::f ()
{
// blahblah
}

Still,there is no way to"partially specialize the function for the class.

If else how do i specialise just this fn/?


Just like Victor said, overload.Or make the function templated if the design
allows.

Hi Template partial specialization always seems like a fairly straightforward concept - until I try to do it :). I am trying to implement the input sequence type (from Stroustrup section 18.3.1, 'Iseq'). I want the version for containers that he gives, but also to provide a specialization for construction from a pair<It,It> (eg because that is returned by equal_range()).

Your expertise will be appreciated... Here's a general templatised class; all specialisations of this class should have a pointer to a specialisation of the same, templatised type: template<typename T, const int N> struct Base : T { typedef Base<T, N> Type;

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
