I've been watching your videos for help in my computer systems class, and your content is the BEST there is on TH-cam my friend. Thank you for creating such succinct, intuitive content for those learning the C language!

[@PortfolioCourses]

You're welcome! :-) Thank you so much for taking the time to leave such positive feedback, it's much appreciated. I see it's a couple of years ago now, but congratulations on getting into Stanford, that's very exciting.

[@Alp-yp5un]

Very good explanation... however I came across a small mistake @ 6:41 where you said "memcpy" instead of "memmove." Just thought making this clear in the commend section will help others get less confused. Other than that thanks a lot for your great content

[@mouadflp1480]

thank you man , your awesome, give us some tut about MAKEFILE please

[@PortfolioCourses]

Thanks Mouad, that one gets requested a lot, I'm hoping to do that topic one day. :-)

[@christianonuegbu1587]

Please makefile, I vote for it too Ur explanation is superb

[@PortfolioCourses]

I still really want to do a makefile tutorial one day, unfortunately that's "a big one" to do so I haven't had time yet.

[@-chaaoui7552]

Well explained. Can you do a video about makefile in the future.

[@PortfolioCourses]

Yes, one day I will do a video on makefiles for sure. It's a big topic so perhaps I will start with an introduction video first to introduce the concept. 🙂

[@natevaub]

Thanks for all your video :)

[@PortfolioCourses]

You're welcome Nathan! 🙂

Thank you! :-)

[@thebestteacher7466]

how to create my own memmove function?

[@PortfolioCourses]

I don't have a video covering that yet unfortunately. You might be able to find some sources online like this one to help: aticleworld.com/memmove-function-implementation-in-c/. :-)

[@ousamahaddadi1032]

make the Makefile video please , we already understand it , but we want to watch your explanation though

[@PortfolioCourses]

I want to do a video on makefiles for sure Ousama, the problem is that one will take a fair bit of time to create. I need a day with a lot of time free to make that video, and I may not get a day like that until December or January. :-(

thank u kevin
but they are actually giving the same results when memory overlaps even with big buffer

[@PortfolioCourses]

memmove() guarantees the correct behaviour, memcpy() does not guarantee the correct behaviour, that is the difference. So memcpy() might work or it might not. :-)

[@justcurious1940]

@@PortfolioCourses thank u for replying
should we expect an implementation for this function ?

[@PortfolioCourses]

Hopefully one day yes! :-)
