there really is some small channel out there, unoticed by many but offers gold knowledgeable content, this channel is one of those, still at the first episodes and I already love what I learned.

10:53 ok this absolutely blew my mind!

[abhi-]

Such good grasp on content. Wow. Thanks for the videos.

Thank you! Your telling is blazingly clear!

[hengtan]

Great c++ metaprogramming tutorial. I so glad I finally found it

[dominikwyss]

Thank you for all your hard work! Your channel is super helpful!

[thestarinthesky_]

wow! you're awesome or what! Just discovered you. Thank you great video!

[helloworld]

your knownledge is helpul so i'm subscribe your channel, keep spirit and Don't get tired of helping people😊😉

Audio quality is not good but nvm content is great on your channel. Looking forward for more content on C++ from you. Gonna recommend to others also.

strip_pointer can also be implemented by recursion!

template<typename T>
struct strip_pointer{
using type = T;
};

template<typename T>
struct strip_pointer<T*>{
using type = typename strip_pointer<T>::type;
};

Do you have a video covering concepts in C++20? Great video btw

[maryguty]

so what about double pointers? how would one treat that?

[muhammadwaleedbinkhalid]

Thanks for the video.

At 15:33 line 26, only works for c++20. For older version we have to use:

using T_without_pointer = typename strip_pointer<T>::type;

Otherwise I get the error: need 'typename' before 'strip_pointer<T>::type' because 'strip_pointer<T>' is a dependent scope

Could someone explain why this is the case? Thanks

Oh my goodness, the audio quality.... Please put your videos in an editor like Davinci Resolve or Shotcut or something and play with some EQ, Compression, or at least hit the normalize button. Also, do not point the mic at your throat, we can hear every single drop of saliva.

next time try to speak more clearly its difficult to understand you
