Template Specialization In C++

[@treyquattro]

so here's a question: what are the relative merits and disadvantages of providing the functionality in the video via: 1. using a template specialization 2. using a non-template function predicated on the specialized type (basically the addAll string specialization but drop the template 3. compile-time specialization in the ordinary template version via if constexpr(...) (put the extra string-specific code in compile-time conditional blocks) I think if the algorithm is substantially the same then option 3 above is a good solution: we want to avoid copying code as much as possible (ODR). Thoughts?

great job would be better if u have shown an example for class template specialization too

[@CppNuts]

Thanks man!!

[@SimplySpiceIt]

addAll() could have taken the std::vector as const-ref(no reason to work with the copy); on the other hand, primitive types, you doN't need that, just copy( for(T element: list)). count should have been std::vector::size_type. Other than that, to demonstrate the concept, the given example is fine.

Hi Paterolen Exactly!!

[@CppNuts]

@@SimplySpiceIt, may be we didn't understood you correctly, please provide some working example of what are you trying to explain here. (paste working code here)

[@SimplySpiceIt]

@@CppNuts Apologies. I took the literal meaning of `count`, All that you doing a simple summation of elements, where we must use T as the @Paterolen mentioned. However, the identifier count made all confusion.

[@SimplySpiceIt]

@@CppNuts However, my first two points are still valid. Here is what you could have done instead: template T addAll(const std::vector &list) { return std::accumulate(list.cbegin(), list.cend(), static_cast(0)); } template std::string addAll(const std::vector &list) { std::size_t sum = 0; // naming made all confusion for (const std::string &str : list) for (const char chr : str) sum += chr; return std::to_string(sum); } int main() { std::cout

[@qureshiowais6951]

is this function overloading?

[@ChandanKr.16]

Kindly make one long video for templates

[@CppNuts]

Ok I will try

What is: for(auto& elem: list)

[@CppNuts]

Here is my video it's called range-based for loop. kzbin.info/www/bejne/mqfEon-kl8l4ma8

[@enzomannaert7324]

A ranged based for loop, it goes over every element in de list.

Excellent !!

Thanks!!

Thanks for the nice video, but too many ads come while you are watching!

[@CppNuts]

Sorry man, that's all I can say.

[@ramezanikebrya]

@@CppNuts No problem. Thanks for the interesting video.

[@mockingbird3809]

Amazing video! Do we have a Discord? (or IRC)

[@tinuchoudhary.]

Could you explain in hindi

[@CppNuts]

I can but i have to create new channel for that..

[@gayathrichagani665]

Video is not clear the screen is full blurr sir. Please make sure that your video is clear

[@CppNuts]

KZbin have reduced the resolution for mobiles if you want to see e good quality video please please watch it from computer.
